	* src/cairo.c:

2005-08-13  Carl Worth  <cworth@cworth.org>

	deadlocks have disappeared as of the cairo_scaled_font_map patch
	from two days ago.
	
	* configure.in: Setup an automake conditional for the HAVE_PTHREAD
	case.
	
	* test/Makefile.am: Link all tests with -lpthread if available, so

2005-08-13  Behdad Esfahbod  <behdad@behdad.org>

	* src/cairo-color.c: Fix conversion to short, to get a uniform
	range even for 0xffff.  In other words, a color component of
	of (1.0 - epsilon) would convert to 0xffff, not 0xfffe.

2005-08-13  Behdad Esfahbod  <behdad@behdad.org>

	* RELEASING:

2005-08-10  Carl Worth  <cworth@cworth.org>

	From Keith Packard <keithp@keithp.com>,

	* cairo.pc.in: Drop libpixman from Requires.
	
	* configure.in: Don't check for libpixman. Check version of

	pixman functions from the various fb, Fb, INT_pixman, pixman,
	Render, _Render, or no prefix to _cairo_pixman_ prefixes.

	(_cairo_simple_font_cache_create_entry),

	that are not cairo's fault as zeroing the buffer before writing
	the png image actually causes more errors(!). And, notably,
	setting all the data to random bytes usually makes the errors go
	away.
	
	* test/Makefile.am: Change the check-valgrind target to include
	the .valgrind-suppresions file and to tee output into
	valgrind.log.

2005-08-14  Stuart Parmenter  <pavlov@pavlov.net>

	* src/cairo-win32-surface.c: (_cairo_win32_surface_fill_rectangles): 
	blue and green values were swapped in the DO_SOURCE case.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* test/cairo-test.c: (cairo_test_create_png_pattern): Rewrite to
	use cairo_image_surface_create_from_png rather than custom
	read_png_argb32. In addition to being simpler, this eliminates the

2005-07-14  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h:
	* src/cairo-pattern.c: (_cairo_pattern_release_surface): Fix to
	accept a cairo_pattern_t rather than a cairo_surface_t as the
	primary argument.

	* src/cairo-image-surface.c: (_cairo_image_surface_composite),
	(_cairo_image_surface_composite_trapezoids): Track change in
	_cairo_pattern_release_surface and also pass the appropriate
	pattern for each acquired surface. The previous backend mismatch
	was causing memory leaks.

	* src/cairo-xlib-surface.c: (_get_image_surface): Remove stale
	comment.

	* test/xlib-surface.c: (main): Add missing fclose to keep valgrind
	happy about memory leaks.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* test/cairo-test.c: (cairo_test_expecting),

2005-07-14  Carl Worth  <cworth@cworth.org>

	* test/cairo-test.c: (cairo_test_real): Fix comment describing
	test result. It's not enough that all tested backends are
	successful. We also require that at least one backend is actually
	tested.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* test/cairo-test.c: (cairo_test_for_target), (cairo_test_real):
	* test/cairo-test.h: Don't consider a test to fail if it can't
	create a surface at all (eg. no X server is available). Instead
	mark this backend as untested and only consider the overall test a
	success if all tested backend are successful.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* src/cairo-ps-surface.c: (pattern_is_translucent): Add missing
	(putatively unreachable) return value.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* src/cairo-image-surface.c:
	(_cairo_image_surface_set_clip_region): Remove the copying of the
	region. This was a workaround for a missing copy bug in libpixman
	that has since been fixed. So now it was just a memory leak.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* src/cairo-png.c (read_png): Patch memory leak of png_info
	object.

2005-07-14  Carl Worth  <cworth@cworth.org>

	cairo_image_surface_create_from_png function.

2005-07-14  Carl Worth  <cworth@cworth.org>

	* src/cairo-meta-surface.c: (_cairo_meta_surface_replay): Use
	the _cairo_surface_*() functions when replaying.
	
	* src/cairo-ps-surface.c: Fold the "locate fallbacks" pass into
	the postscript output pass, and add a simple, first implementation
	of image fallbacks.

2005-07-13  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h:
	* src/cairo-font.c: (_cairo_simple_font_face_create_font): Rename
	CAIRO_FONT_BACKEND_DEFAULT to the more accurate
	CAIRO_SCALED_FONT_BACKEND_DEFAULT.

2005-07-13  Carl Worth  <cworth@cworth.org>

	* src/cairo-ft-private.h:

	rather than just blindly assuming that's what we get.

2005-07-12  Carl Worth  <cworth@cworth.org>

	* src/cairo-hash-private.h:
	* src/cairo-hash.c:
	(_cairo_hash_table_create): Remove destroy notifier. This
	simplifies the implementation a bit, and no anticipated use of
	cairo_hash_table_t in cairo needs the destroy notifier. Most uses
	will be hash-backed object create/destroy functions.
	
	(_cairo_hash_table_destroy): Document that it is now a fatal
	error to call _cairo_hash_table_destroy on a non-empty hash table.

	(_cairo_hash_table_insert): Document that it is now a fatal
	error to insert an entry with a key that matches an existing
	entry.

	(_cairo_hash_table_random_entry): Add predicate function so that
	the user can select a random entry satisying the given predicate.

	(_cairo_hash_table_remove): Change return type to void since
	failure is really not possible here.

2005-07-11  Carl Worth  <cworth@cworth.org>

	* ROADMAP: Add cache lock deadlock problem to roadmap for 0.5.2.
	Fix typo (cairo_ft_options_t -> cairo_font_options_t).
	Add note that glyph measurement performance needs to improve.

	* src/cairoint.h: Disable mutex locks, (making the caches
	non-thread-safe again, just like they were in the last snapshot
	and before).

2005-07-11  Carl Worth  <cworth@cworth.org>

	* ROADMAP: Note that the cairo_content_t work is done.
	Note progress on cairo_meta_surface_t, ARGB text, and group
	support.
	Add recent API change proposals (cairo_ft_options_t,
	cairo_xlib_surface_create needs to be screen aware, and
	cairo_xlib_surface_set_drawable).

	* src/cairo-arc.c (_arc_segments_needed): Note that this function
	is computing an incorrect result.

2005-07-08  Carl Worth  <cworth@cworth.org>

	* src/cairo.h: Give enum tags an underscore prefix to match the
	style of the struct tags. Add new cairo_content_t and change
	cairo_surface_create_similar to accept a cairo_content_t rather
	than a cairo_format_t.

	* src/cairo-gstate.c:
	(_cairo_gstate_clip_and_composite_trapezoids),
	(_cairo_gstate_copy_page), (_cairo_gstate_show_page): Don't check
	for gstate->target == NULL anymore as the API now guarantees it
	never occurs.
	
	* src/cairo.c: (cairo_append_path): Check that path->status is a
	valid status value and cause an INVALID_STATUS error otherwise.

	* test/path-data.c: (main): Test the new
	CAIRO_STATUS_INVALID_STATUS error case in cairo_append_path.

2005-07-06  Carl Worth  <cworth@cworth.org>

	* configure.in: Require libpixman >= 0.1.5, (since 0.1.4 crashes
	on some X servers).

2005-07-05  Carl Worth  <cworth@cworth.org>

	* src/cairo-ps-surface.c: Disable the compilation of the

	appears to not currently be used.

2005-07-04  David Reveman  <davidr@novell.com>

	pattern creation.

2005-07-01  Kristian Høgsberg  <krh@redhat.com>

	* src/cairo-ps-surface.c: Rewrite postscript backend to generate
	more interesting output than the current big-image implementation,
	using meta surfaces for font subsetting and image fallbacks.
	
	* src/cairo-meta-surface.c: Remove obsolete comment.
	
	* src/cairoint.h:
	* src/cairo-output-stream.c: Make a couple of stylistic changes
	and add _cairo_output_stream_write_hex_string.
	
	* src/cairo-surface.c: Add _cairo_surface_intersect_clip_path so
	we can replay path clipping.

	(_cairo_hash_table_insert), (_cairo_hash_table_remove),
	(_cairo_hash_table_foreach): Rewrite hash table to use a single
	cairo_hash_entry_t* rather than void *key and void *value. This is
	slightly more painful to use, but lends itself to a more
	memory-efficient implementation. Add documentation.

2005-06-29  Carl Worth  <cworth@cworth.org>

	(_cairo_hash_table_lookup), (_cairo_hash_table_insert),
	(_cairo_hash_table_remove), (_cairo_hash_table_foreach): Rework
	the cache code as a hast table with a much simpler interface, (no
	object derviation is required to use it).
	
	* src/cairoint.h: Remove extraneous prototype for non-existent
	_cairo_cache_reference.

2005-06-28  Kristian Høgsberg  <krh@redhat.com>

	* src/cairo-pattern.c (cairo_pattern_create_rgb)

	Change global glyph and xlib glyphset caches behaviour to only
	shrink cache on unlock.  This is done by telling the cache code to

	Fix Carl's variable renaming mixing (cache = cache).

	* src/cairo-xlib-surface.c: Detect servers with a bug in 
	repeating surfaces by checking vendor string and version.

	an implementation with the core protocol or fall back to the image
	backend.

	* src/cairo-xlib-surface.c: Save clip rects when setting a
	clip region on a surface so that we set the right clip for the

	* src/cairo.h:
	* src/cairo-private.h:
	* src/cairo.c: (_cairo_error), (cairo_create): Rip out
	cairo_set_error_notfiy function as it is clear that it is not the
	right approach.

	* test/.cvsignore:
	* test/Makefile.am:
	* test/error-notify.c: Remove error-notify test.

2005-06-17  Carl Worth  <cworth@cworth.org>

2005-06-17  Carl Worth  <cworth@cworth.org>

	* src/cairo.c: (cairo_reference), (cairo_destroy): cairo_reference
	and cairo_destroy shouldn't behave differently when cr->status
	indicates an error. Fix this bug that just slipped back in.

	* src/cairo.c: (cairo_restore): Remove useless conditional return
	at the end of a void function.

	* src/cairo.c: (cairo_get_source), (cairo_get_font_face),

2005-06-17  Kristian Høgsberg  <krh@redhat.com>

	* TODO: Remove the path clipping entry from the list.

2005-06-16  Carl Worth  <cworth@cworth.org>

2005-06-15  Owen Taylor  <otaylor@redhat.com>

	* doc/public/Makefile.am (MKTMPL_OPTIONS): Remove --only-section-tmpl;
	it doesn't really work currently :-(.

2005-06-15  Owen Taylor  <otaylor@redhat.com>

	* src/cairo-gstate.c (_cairo_gstate_clip_and_composite_trapezoids):
	Use a clip region when rendering a non-solid pattern through
	a rectangular path ... trapezoid rasterization is just too slow
	to use that path when we aren't forced to do so.

2005-06-15  Carl Worth  <cworth@cworth.org>

	* test/cairo-test.c: Track removal of cairo_status_string.
	(cairo_test_for_target): And add missing parenthesis.

2005-06-15  Carl Worth  <cworth@cworth.org>

	* TODO: Add cairo_finish to TODO list. Note that

2005-06-15  Carl Worth  <cworth@cworth.org>

	* src/cairo.h:
	* src/cairo.c: Remove cairo_status_string function which can now
	be replaced by:

		cairo_status_to_string (cairo_status (cr));

	This allows consistent handling of status values for things like
	cairo_pattern_status where there is now
	cairo_pattern_status_string function.

2005-06-13  Carl Worth  <cworth@cworth.org>

	* src/cairo.c: (_cairo_error): Add _cairo_error so we have a
	single function which all errors can pass through. This allows the
	user to set a breakpoint on error and will allow us to augment
	error handling later as necessary.

2005-06-15  Carl Worth  <cworth@cworth.org>

	* doc/public/cairo-sections.txt: Remove cairo-atsui section since
	cairo-atsui.h is currently empty.
	Add cairo_path_data_type_t and cairo_path_data_t.

	* test/.cvsignore: Add pdf-clip and pdf-clip.pdf.

	(_cairo_xlib_surface_clone_similar):
	* src/cairoint.h: Remove Boolean 'drawable' parameter from the

	actually using this parameter.

2005-06-14  T Rowley  <tim.rowley@gmail.com>

	* src/cairo-win32-font.c: Correct extents for text with a general
	tranform.

2005-06-14  Carl Worth  <cworth@cworth.org>

	* src/cairo.h: Remove comment suggesting ambiguity of whether
	cairo_get_target references the surface, (we decided as part of
	the API shakeup that cairo functions returning pointers to
	internal objects do not automatically take a reference).

2005-06-13  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h:
	* src/cairo-pattern.c: (_cairo_pattern_create_in_error): Add new
	_cairo_pattern_create_in_error.

	* src/cairo.c: (cairo_get_source): Propagate error values from
	cr->status to pattern->status.

2005-06-13  Carl Worth  <cworth@cworth.org>

	* src/cairo.c (_cairo_set_source_solid),
	(cairo_set_source_surface), (cairo_mask_surface): No longer need
	to check for NULL after creating a pattern.

	* src/cairo.c (cairo_set_source), (cairo_mask): Propagate status
	errors from pattern->status to cr->status.
	
	Originally 2005-05-08  Owen Taylor  <otaylor@redhat.com>:
	
	* src/cairo-pattern.c src/cairoint.h: If allocation of pattern
	objects fails, return special static nil pattern objects.
	
	* src/cairo-pattern.c: If adding a color stop fails to allocate
	memory, set pattern->status. (And fix a memory leak.) Make public
	functions return when pattern->status is set, (and no longer
	return a cairo_status_t).

	* src/cairo-pattern.c src/cairo.h doc/public/cairo-sections.txt:
	Add cairo_pattern_status()

	* src/cairo-gstate.c: Check the status of gstate->source and
	of mask patterns passed in.

2005-06-13  Carl Worth  <cworth@cworth.org>

	Originally 2005-05-08  Owen Taylor  <otaylor@redhat.com>:

	* src/cairo.c (cairo_create): If cairo_create() fails, return
	a special static object, cairo_nil.

	* src/cairo.c (cairo_reference): Don't return early if 
	cr->status is set. cr->status should not affect reference
	counting.

	* src/cairo.c: (cairo_reference), (cairo_destroy): Ignore any
	magic object with a reference count of -1.

2005-06-13  Carl Worth  <cworth@cworth.org>

	Originally 2005-06-02  Carl Worth  <cworth@cworth.org>:

	* src/cairo.h: Add a status field to cairo_path_t.

	* src/cairo.c:
	(cairo_copy_path), (cairo_copy_path_flat): Add documentation for
	the new approach for handling errors in these functions---always
	returning a valid pointer with at least a status.
	(cairo_append_path): Propagate path status errors to the
	context. Add note to documentation on initializing path->status.

	* src/cairo-path-data-private.h: Add missing cairo_private
	qualifier to a couple functions.
	
	* src/cairo-path-data.c: (_cairo_path_data_create_real): Track new
	status field in cairo_path_t.
	(cairo_path_destroy): Don't destroy cairo_path_nil. Add
	documentation.
	(_cairo_path_data_create):
	(_cairo_path_data_create_flat):
	(_cairo_path_data_append_to_context): Add documentation.
	(_cairo_path_data_create_in_error): New function to create a
	placeholder cairo_path_t just to propagate a cairo_status_t error.

2005-06-11  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h:
	* src/cairo-gstate.c: (_cairo_gstate_init,
	_cairo_gstate_init_copy, _cairo_gstate_fini): Make these functions
	static, which allows slightly less awkward error handling within
	them.

2005-06-10  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h: Provide font-backend-specific macros for
	FONT_FAMILY_DEFAULT. Change CAIRO_FT_FONT_FAMILY_DEFAULT from
	"serif" to "" to allow the actual default to come from the
	system/user configuration.

2005-06-10  Carl Worth  <cworth@cworth.org>

	* src/cairo.h: Pull the enum out from inside cairo_path_data_t and
	give it a name of cairo_path_data_type_t. This allows C++ programs
	to see the enum values. It also allows variables to be declared of
	this type for manually constructing a cairo_path_t.

2005-06-10  Carl Worth  <cworth@cworth.org>

	* ROADMAP: Add 'consistent error handling' to 1.0 roadmap. (This
	isn't new, we just forgot to list it here before).

	* TODO: Big cleanup to remove finished items. Also, split the file
	up to separate TODO items that affect the API from items that do
	not.

2005-06-10  Carl Worth  <cworth@cworth.org>

2005-06-09  Carl Worth  <cworth@cworth.org>

	* src/cairo.h: Remove trailing comma from enum values which gcc
	4.0 does not want to see (Luis Villa). Closes bug #3502.

2005-06-09  Owen Taylor  <otaylor@redhat.com>

	* test/Makefile.am (INCLUDES): Add 
	-I$(top_builddir)/src for cairo-features.h (Tomasz Cholewo)
	
2005-06-07  Keith Packard  <keithp@keithp.com>

	* src/cairo-pdf-surface.c: (_cairo_pdf_surface_show_glyphs):
	Font matrix was output incorrectly; the implicit mirror-in-y
	transformation was not computed correctly, missing a negation
	of the 'xy' component.

2005-06-02  Kristian Høgsberg  <krh@redhat.com>
 
	* src/cairo-gstate.c (_cairo_gstate_clip): When clipping, update

	* src/cairo-atsui-font.c: (_cairo_atsui_font_destroy_font): Remove

2005-06-03  Carl Worth  <cworth@cworth.org>

	* src/cairoint.h:

	everything could be changed to match it instead. I'll save that
	for some day when we're cleaning up the cache code.

2005-06-03  Carl Worth  <cworth@cworth.org>

	* src/cairo-gstate.c: (_cairo_gstate_init): Remove obsolete
	_cairo_gstate_set_target_surface, folding its contents into

2005-05-26  Keith Packard  <keithp@keithp.com>

	reviewed by: krh, otaylor, cworth

	Replace nesting-only surface clipping with gstate contained
	serial-number tracked clipping sets that are loaded into the surface
	on demand just before each rendering operation.  This permits
	multiple cairo_t contexts to reference a surface without
	regard to ordering of operations among the contexts.

	Also in this patch is a change to the xlib surface that
	creates two separate Pictures, one for source and one for
	destination operands which separates the source clipping
	from destination clipping.  Cairo now specifies that sources
	are never clipped by any clipping applied to them as destinations.

	* src/cairoint.h:
	* src/cairo-gstate-private.h:
	Move cairo_clip_t (renamed from cairo_clip_rec_t) from cairoint.h
	to cairo-gstate-private.h.  Eliminate stack of clip state
	from surfaces.  Add new surface clipping API.
	
	* src/cairo-gstate.c: (_cairo_gstate_init),
	(_cairo_gstate_init_copy), (_cairo_gstate_fini),
	(_cairo_gstate_has_surface_clip), (_cairo_gstate_set_clip),

	(_cairo_gstate_fill), (_cairo_gstate_reset_clip),
	(_cairo_gstate_clip), (_cairo_gstate_show_glyphs):
	Manage clip objects entirely within the gstate, loading
	the whole thing into the surface just before drawing.
	
	* src/cairo-pattern.c:
	(_cairo_pattern_acquire_surface_for_gradient),
	(_cairo_pattern_acquire_surface_for_solid),
	(_cairo_pattern_acquire_surface_for_surface),
	(_cairo_pattern_acquire_surface), (_cairo_pattern_release_surface):
	Source surfaces need not have clipping modified as the
	surface interface now specifies that source surfaces are always
	unclipped.
	
	* src/cairo-surface.c: (_cairo_surface_init),
	(cairo_surface_finish), (_cairo_surface_clone_similar),
	(_cairo_surface_get_current_clip_serial),
	(_cairo_surface_allocate_clip_serial), (_cairo_surface_reset_clip),
	(_cairo_surface_can_clip_region), (_cairo_surface_set_clip_region),
	(_cairo_surface_can_clip_path), (_cairo_surface_clip_path),
	(_cairo_surface_get_extents):
	Eliminate nested clipping contexts, leaving clip management
	entirely to the gstate.  Create new clip API for the gstate
	which uses per-surface serial numbers to match gstate clipping
	against current surface clipping values.
	
	Surfaces no longer track clipping regions at all, so the
	old _cairo_surface_get_clip_extents has been replaced with
	_cairo_surface_get_extents.  For PDF/PS surfaces, this
	function is expected to return a rectangle covering the
	entire fixed point coordinate space to leave rendering
	unclipped by the surface.
	
	* src/cairo-xcb-surface.c:
	Region clipping capability is now signalled by a non-NULL
	function pointer in set_clip_region.
	
	* src/cairo-xlib-surface.c: (_cairo_xlib_surface_finish),
	(_cairo_xlib_surface_ensure_src_picture),
	(_cairo_xlib_surface_ensure_dst_picture),

	(_cairo_xlib_surface_show_glyphs32),
	(_cairo_xlib_surface_show_glyphs16),
	(_cairo_xlib_surface_show_glyphs8),
	(_cairo_xlib_surface_show_glyphs):
	Each surface now contains two Pictures, one for source
	and one for destination operands so that source operands
	are never clipped by destination clipping.

	* src/cairo.h:
	* src/cairo.c: (cairo_status_string):
	CAIRO_STATUS_BAD_NESTING removed
	
	* test/Makefile.am:
	* test/self-copy.c: (main):
	self-copy now passes (Xlib only, until libpixman changes land)

	Rework of cairo_xlib_surface create functions by Keith Packard:

	Add cairo_xlib_surface_create_with_render_format.
	
	* src/cairo-xlib.h:
	* src/cairo-xlib-surface.c:
	(cairo_xlib_surface_create),

	width_in_points, height_in_points for better clarity.

	* src/cairo-ps.h:
	* src/cairo-ps-surface.c: Brush a bunch of dust off of the PS
	backend and bring it up to date with the latest API conventions
	from the PDF backend. These include: accepting a filename rather
	than a FILE in the primary constructor, providing a stream-based
	interface for more flexibility, and accepting a surface size in
	device-space units (points) rather than inches.

	* test/pdf-surface.c: (main): Make it a little more clear that the
	width and height being passed around are in units of points.
	
	* test/ps-surface.c: (main): Update to the latest cairo-ps.h
	changes as described above. Notice how much more sane things
	become now that the surface size is described in device-space
	units.

2005-05-16  Keith Packard  <keithp@keithp.com>

	* src/cairo-pattern.c: (_cairo_pattern_shader_init):
	Initialize op->stops[0].scale = 0.  
	
	This scale value is used only when computing gradient values
	before the defined range, in which case stop 0 is used for both
	ends of the interpolation, making the value of 'scale' not
	actually matter, except that valgrind notices we're using
	an undefined value.

2005-01-27  Kristian Høgsberg  <krh@redhat.com>

	The overall idea of this rewrite is that we want to pass the
	source pattern all the way down into the backends.  The motivation
	for this is that not all backends want a surface for the source
	operand, and by passing the pattern down, backends can choose to
	convert it to a surface if they need that.

	The patch removes the create_surface function pointer from the
	surface vtable and moves much of that code into a couple of helper
	functions.  The composite, compsite_trapezoids, and show_glyphs
	backend functions are updated to take a cairo_pattern_t instead of
	a surface as the source.
	
	* src/cairo_font.c: (_cairo_font_show_glyphs):

	(_cairo_gstate_show_glyphs):
	Change these functions to not create a surface for the pattern and
	just pass the pattern down to the backend functions.
	
	* src/cairo_gstate.c: (translate_traps):
	New function to translate a set of trapezoids.
	
	* src/cairo_pattern.c:
	(_cairo_pattern_init),
	(_cairo_pattern_init_copy),
	(_cairo_pattern_prepare_surface),
	(_cairo_pattern_restore_surface):
	Break out the code to adjust and restore surface transformation
	and repeat settings into _cairo_pattern_prepare_surface and
	_cairo_pattern_restore_surface.
	
	* src/cairo_pattern.c: (_cairo_pattern_fini),
	(_cairo_pattern_init_for_surface),
	(cairo_pattern_create_for_surface):
	Split cairo_pattern_create_for_surface into an init function and a
	create function.

	cairo_font_set_transform and cairo_font_current_transform,
	segfault on AMD64.

	loop-independence.

2004-11-08  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	${srcdir} so that make distcheck will work.

	* test/Makefile.am (cairo_test_lib): Add header files so that make
	distcheck is happy.

	* src/cairo_ft_font.c (_cairo_ft_font_glyph_path):
	(_cairo_ft_font_text_path): A couple of changes missed in the last
	batch of commits (reordering so that path is final argument).

	* src/cairoint.h: Change cairo_font_backend_t to use a void * for
	the abstract font. Put create, copy, and destroy as the first
	functions in the list. Fix text_path and glyph_path so that the
	path to be returned is the last argument. Add x,y arguments to
	text_path.

	* src/cairo_gstate.c (_cairo_gstate_text_path): Compute x,y now
	needed by cairo_font_text_path.
	(_cairo_gstate_glyph_path): Track change in

		descent (replaced by) height

2003-12-15  Carl Worth  <cworth@isi.edu>

	* src/cairo_gstate.c (_cairo_gstate_text_extents):
	(_cairo_gstate_glyph_extents): Need to divide out the scale factor
	to return user-space extents.
	(_cairo_gstate_glyph_extents): Don't transform glyph locations as
	they're not relevant to extents.

	* src/cairo_ft_font.c (_cairo_ft_font_font_extents): Clean up
	implementation.
	(_cairo_ft_font_glyph_extents): Initial implementation. Thanks to
	John Ellson <ellson@research.att.com> for most of the work on this
	function.
	(_cairo_ft_font_show_text): Clean to use num_glyphs not nglyphs.

	* src/cairo.h:

	(cairo_ft_font_backend): Remove evil void * casts on function
	pointers.

	* src/cairo_font.c (_cairo_font_show_glyphs): Fix to not require a
	current point.

	* src/cairo_gstate.c (_cairo_gstate_show_text):
	(setup_text_rendering_context): Move initialization of current
	device-space point from setup_text_rendering_context to
	_cairo_gstate_show_text.
	(_cairo_gstate_show_glyphs): Fix to not reference current point.

2003-12-12  Dave Beckett  <Dave.Beckett@bristol.ac.uk>

	* src/Makefile.am: Add compatibility defines FONTCONFIG_LIBS,
	X_LIBS, XRENDER_LIBS to keep automake happy - they look like
	automake variable names.

2003-12-12  Carl Worth  <cworth@east.isi.edu>

	* src/cairo_font.c (_cairo_font_create): Add comment about
	building in a font.

	slim_import.h.

2003-12-11  Carl Worth  <cworth@isi.edu>

	* src/cairoint.h: Rename surface->ic_image to

	(_cairo_image_surface_fill_rectangles):
	(_cairo_image_surface_composite_trapezoids): Rename functions and
	indentifiers with ic_ in the name that were missed by the recent
	renaming. Fix indentation problems left by the recent renaming.

	* Shift everything over from libic/libpixregion/slim to
	libpixman. Many thanks to Dave Beckett
	<dave.beckett@bristol.ac.uk> for all of the heavy lifting with
	this renaming effort.

	* src/cairoint.h (slim_hidden_proto1): Directly fold in slim stuff
	rather than depending on it from an external package.

	* src/cairo_ps_surface.c (_cairo_ps_surface_copy_page): 
	* src/cairo_image_surface.c: Switch from libic to libpixman.

	* src/cairo.h: Include pixman.h not ic.h.

	 _cairo_ft_font_create:
	 _cairo_gstate_select_font:
	 	change char * family to const char * family

2003-12-11  Carl Worth  <cworth@isi.edu>

	* src/cairo_xlib_surface.c (_cairo_xlib_surface_set_image):
	Replace mysterious image->depth == 32 ? 24 : image->depth with
	simply image->depth.

2003-12-11  Carl Worth  <cworth@east.isi.edu>

	* cairo.pc.in (Requires): 
	* configure.in: Add xrender to cairo.pc Renders line if needed.

2003-12-11  Carl Worth  <cworth@east.isi.edu>

	* src/cairo_ps_surface.c (_cairo_ps_surface_copy_page): Fix to use
	shifts and masks for endianness-correct PS image
	generation. Rename bgr to rgb now that the byte order issues are
	clear.

2003-12-08  Carl Worth  <cworth@isi.edu>

	* src/cairo_path_bounds.c (_cairo_path_bounder_move_to):
	(_cairo_path_bounder_line_to):
	(_cairo_path_bounder_curve_to):

	* src/cairo_path_fill.c: 
	* src/cairo_path.c: Clean up cairo_path_callbacks to have move_to,
	line_to, curve_to, abd close_path instead of add_edge, add_spline,
	and done_sub_path. Much, much nicer.

	* src/cairo_polygon.c (_cairo_polygon_move_to): Provide
	cairo_polygon_move_to and cairo_polygon_line_to instead of
	cairo_polygon_add_point.

	* src/cairo_pen.c (_cairo_pen_stroke_spline_half): Track change in
	cairo_polygon interface.

2003-12-08  Carl Worth  <cworth@isi.edu>

	* configure.in: Bump version to 0.1.16 since it actually has a
	hope of building, (due to fix for broken cairo-xlib.h includes).

2003-12-05  Carl Worth  <cworth@east.isi.edu>

	* src/cairo_xlib_surface.c: Don't include obsolete cairo-xlib.h.

	* autogen.sh (AUTOCONF): Allow names of all autofoo programs to be
	overridden via environment variables.

	* configure.in: Bump version to 0.1.15 for new
	CAIRO_HAS_XLIB_SURFACE macro.

	* src/cairo.h: Add missing #include <cairo-features.h>

	* Rename cairo-config.h to cairo-features.h.

	* configure.in: Rename XLIB_BACKEND_DEFINE to
	XLIB_SURFACE_FEATURE. Rename AM_CONDITIONAL HAVE_XLIB_BACKEND to
	CAIRO_HAS_XLIB_SURFACE. Rename user-visibile macro
	CAIRO_HAS_XLIB_BACKEND to CAIRO_HAS_XLIB_SURFACE.

2003-12-03  Carl Worth  <cworth@east.isi.edu>

	* configure.in: Bumped version to 0.1.14 to indicate dropped
	cairo-xlib.h and new cairo-config.h.

	* New support for "./configure --without-x" to compile without the
	xlib backend. Many thanks to Sasha V. <sasha@aftercode.net>.
	
	* configure.in: We do three things here: Make the pkg-config check
	for xrender conditional, set XLIB_BACKEND_DEFINE to either
	CAIRO_HAS_XLIB_BACKEND or CAIRO_HAS_NO_XLIB_BACKEND to be
	substituted into cairo-config.h, and set an AM_CONDITIONAL for
	HAVE_XLIB_BACKEND to enable conditional compilation of
	cairo_xlib_surface.c.  Perhaps that could be simplified a tad, but
	it's what we have working now.  Also split up various
	PKG_CHECK_MODULES into separate checks.

	* src/cairo_gstate.c: Remove errant reference to
	cairo_gstate_set_drawable.

	* src/cairo.h: Move xlib-specific calls in from old cairo-xlib.h,
	now guarded in #ifdef CAIRO_HAS_XLIB_BACKEND.

	* src/Makefile.am (libcairo_xlib_sources): Make compilation of
	cairo_xlib_surface.c conditional.
	(INCLUDES, libcairo_la_LIBADD): Add the new variables from
	splitting up the PKG_CHECK_MODULES calls.

2003-12-03  Carl Worth  <cworth@east.isi.edu>

	* cairo.pc.in (Libs): Add -lz for the compress function used in
	the PS backend.

2003-12-01  Keith Packard  <keithp@keithp.com>

	* TODO:
	Add note about degenerate path caps being broken

2003-11-21  Carl Worth  <cworth@east.isi.edu>

	* src/cairo_polygon.c (_cairo_polygon_add_edge): Use 0 and 1 not
	False and True, (to avoid false dependency on X headers).

	* src/cairo_path_stroke.c (_compute_face): Use
	cairo_point_double_t not XPointDouble, (to avoid false dependency
	on X headers). Thanks to "Sasha V." <sasha@aftercode.net> for
	pointing these out.

2003-11-18  Carl Worth  <cworth@east.isi.edu>

	* configure.in: Bump version to 0.1.13 for new freetype header
	compatibility.
	Fix comments regarding freetype version checking.

2003-11-18  James Henstridge  <james@daa.com.au>

	* cairo.pc.in (Cflags): add FREETYPE_CFLAGS/LIBS to Libs/Cflags
	rather than requiring "freetype2", which doesn't exist in anything
	but the most recent version of freetype.

	* configure.in (FREETYPE_LIBS): add freetype cflags/libs
	substitutions.

2003-11-18  Carl Worth  <cworth@east.isi.edu>

	* src/cairo.h: Fix build for new freetype header include
	mechanism, (thanks to Christof Petig <christof@petig-baender.de>)

2003-11-17  Carl Worth  <cworth@isi.edu>

	* Remove infinite looping when stroking with a line width at or
	close to 0.0. Thanks to Rob Buis <buis@kde.org> and Noah Levitt
	<nlevitt@columbia.edu> for providing in-the-wild examples of SVG
	files with stroke-width:0 that demonstrated the problem,
	(cowboy.svg and albania.svg).

	* src/cairo_pen.c (_cairo_pen_stroke_spline): Do nothing if the
	pen is a degenerate, single point. This happens when the line
	width is a very small, non-zero value.

	* src/cairo_gstate.c (_cairo_gstate_stroke): Do nothing when asked
	to stroke a path with a line_width of 0.0. Previously, this would
	lead to an infinite loop.

	* src/cairo.c (cairo_set_line_width): Force negative line width
	to 0.0.

	* TODO: Updated TODO list.

2003-11-10  Carl Worth  <cworth@east.isi.edu>

	* configure.in: Fix typo (thanks to John Ellson

	* src/cairo.c (cairo_in_stroke):
	(cairo_in_fill): Added new cairo_in_stroke and cairo_in_fill.

	* src/cairo_traps.c (_cairo_trap_contains):
	(_cairo_traps_contain): * src/cairo_gstate.c
	(_cairo_gstate_in_stroke):
	(_cairo_gstate_in_fill): New functions to support for
	cairo_in_stroke and cairo_in_fill. Many thanks to Thomas Hunger
	<info@teh-web.de> for the initial implementation which
	demonstrated how easy this would be and pushed me to go and write
	it already.

	* src/cairo_gstate.c (_cairo_gstate_clip_and_composite_trapezoids):
	* src/cairo_traps.c (_line_segs_intersect_ceil): 
	* src/cairo_path.c (_cairo_path_move_to):
	(_cairo_path_line_to):
	(_cairo_path_curve_to): Fixed to use _cairo_fixed_from_double
	instead of XDoubleToFixed.

2003-11-06  Carl Worth  <cworth@east.isi.edu>

	* src/cairo.c (cairo_current_font): Move declaration to beginning
	of function to avoid requiring a C99-compatible compiler.

	* src/cairo.h: Add comment pondering memory management semantics
	of cairo_current_target_surface.

	* src/cairo_pen.c (_cairo_pen_fini): NULL out pen->vertices after
	free.

	* src/cairo_image_surface.c
	(_cairo_image_abstract_surface_destroy): NULL out durface->data
	after free.

2003-11-04  Carl Worth  <cworth@east.isi.edu>

	* src/cairo_gstate.c (_cairo_gstate_set_target_surface): Enable
	cairo_set_target_surface (cr, NULL) to work. This can be useful to
	force the current target surface to be finalized.

	* configure.in: 
	* cairo.pc.in (Requires): Add explicit fontconfig and freetype2
	dependencies that were implicitly dropped along with Xft.

2003-11-04  Carl Worth  <cworth@isi.edu>

	* TODO: Note that cairo_show_page, cairo_copy_page, PostScript
	backend, "real" text API, and text support for the image backend
	have now all been implemented.

2003-11-04  Carl Worth  <cworth@east.isi.edu>

	* configure.in:
	* cairo.pc.in (Requires): cairo doesn't depend on Xft after the
	recent text work.

2003-11-03  Carl Worth  <cworth@isi.edu>

	* configure.in (CAIRO_VERSION): Bump version to 0.1.11 for new
	cairo_copy_page.

	* src/cairo_ps_surface.c (cairo_ps_surface_create): Now print
	header at time of surface_create rather than in show_page.
	(_cairo_ps_surface_destroy): Print document footer at time of
	surface_destroy rather than in show_page.
	(_cairo_ps_surface_erase): New function for sharing.
	(_cairo_ps_surface_copy_page): Now keep proper page count.
	(_cairo_ps_surface_show_page): Real work is now done in
	copy_page. show_page is only distinct in that it erases the
	surface afterwards.

	* src/cairo.h: 
	* src/cairo.c (cairo_copy_page):
	* src/cairo_gstate.c (_cairo_gstate_copy_page): 
	* src/cairo_surface.c (_cairo_surface_copy_page):
	* src/cairo_image_surface.c (_cairo_image_surface_copy_page): 
	* src/cairo_xlib_surface.c (_cairo_xlib_surface_copy_page): Add
	support for new cairo_copy_page function.

2003-11-03  Carl Worth  <cworth@isi.edu>

	* src/cairo_ps_surface.c (cairo_set_target_ps): Add missing check
	for out of memory.

	* src/cairo_image_surface.c
	(_cairo_image_surface_create_with_masks):
	(_cairo_image_surface_create_with_masks):
	(cairo_image_surface_create):
	(cairo_image_surface_create):
	(cairo_image_surface_create_for_data):
	(cairo_image_surface_create_for_data): Add several missing checks
	for out of memory.

2003-11-03  Carl Worth  <cworth@east.isi.edu>

	* src/cairo.h: Added __external_linkage to a few functions that
	were missing it.

2003-11-01  Carl Worth  <cworth@isi.edu>

	* src/cairo_ps_surface.c (_cairo_ps_surface_show_page): Fix
	misplacement of PS origin, (was translating vertically by width
	instead of height).

	* configure.in (CAIRO_VERSION): Bumped version to 0.1.10 for new
	functions cairo_set_target_ps, cairo_ps_surface_create, and
	cairo_show_page.

	* src/cairo_ps_surface.c: New file with preliminary support for
	drawing to a PostScript file. Most of the ps_surface backend
	functions are just tiny wrappers, deferring to image_surface
	functions to do the real work. Then, in show_page, the image is
	compressed and spit out into the file. Crude and effective.

	* src/cairo.c (cairo_show_page):
	* src/cairo_gstate.c (_cairo_gstate_show_page):
	* src/cairo_image_surface (_cairo_image_surface_show_page):
	* src/cairo_xlib_surface.c (_cairo_xlib_surface_show_page): 
	* src/cairo_surface.c (_cairo_surface_show_page): Implement new
	support for cairo_show_page -- just a stub in the non-PS surfaces.

	* src/cairo_image_surface.c (_cairo_image_surface_set_filter):
	Export this function for internal use.

	* src/cairo.h: Added cairo_set_target_ps, cairo_ps_surface_create,
	and cairo_show_page. Noted plans for new cairo_surface_clip_begin,
	perhaps moving some cairo_surface functions to cairo_set_pattern,
	and possibly renaming cairo_matrix_t to cairo_transform_t.
	
	* src/Makefile.am (libcairo_la_SOURCES): Added cairo_ps_surface.c.

2003-10-31  Carl Worth  <cworth@isi.edu>

	* src/cairo_gstate.c (_cairo_gstate_arc):
	(_cairo_gstate_arc_negative): Do nothing when radius <= 0.0,
	(which is much better than the current infinite loop).

2003-10-31  Carl Worth  <cworth@isi.edu>

	* Moved all libic-related drawing into cairo_image_surface.c.
	Details below:

	* src/cairo_xlib_surface.c: Add width, height, format to
	cairo_xlib_surface_t.
	(_cairo_xlib_surface_get_image):
	(_cairo_xlib_surface_set_image): Implement new get_image/set_image
	interface instead of pull_image/push_image.
	(_cairo_xlib_surface_get_image): Fix memory leak that showed up
	with non-Render servers.
	(_cairo_xlib_surface_set_matrix): Implement set_matrix with new
	interface.
	(_render_operator): Translate from cairo_operator_t to
	Render-defined operator values rather than assuming they are the
	same.

	* src/cairo_surface.c: Move all libic-related code into
	cairo_image_surface.c. cairo_surface is now a thin wrapper around
	concrete surface types, (with fallback code to cairo_image_surface
	whenever a backend does not provide support for a particular
	function). Remove checks for NULL backend functions.
	(_cairo_surface_get_image):
	(_cairo_surface_set_image): New interface to replace
	pull_image/push_image. Now uses a cairo_image_surface rather than
	an IcImage and now also passes it externally rather than storing
	it in the surface.

	* src/cairo_gstate.c (_cairo_gstate_fini):
	(_cairo_gstate_set_target_surface):
	(_cairo_gstate_set_rgb_color): Avoid useless calls to
	cairo_surface_destroy for NULL surfaces.
	(_cairo_gstate_show_surface): 
	(_cairo_gstate_clip): 
	(_cairo_gstate_clip_and_composite_trapezoids):
	(_cairo_gstate_begin_group): Add status checking for calls to
	surface_create_similar, surface_fill_rectangles,
	surface_composite, and surface_composite_trapezoids.

	* src/cairo_ft_font.c (_cairo_ft_font_show_glyphs): Remove one
	gratuitous level of nesting.
	(_cairo_ft_font_show_glyphs): Bubble up NULL_MEMORY status.

	* src/cairo.h: Portability improvements: Remove include of
	X11/extensions/Xrender.h. Move include down near the freetype
	include.
	cairo_format_t: Eliminate Render-based values for this enum.
	cairo_operator_t: Eliminate Render-based values. Drop
	disjoint/conjoint operators.
	cairo_filter_t: Eliminate libic-based values for this enum.
	Add cairo_image_surface_create and cairo_image_surface_create_for_data.

	* src/cairo.c (cairo_status_string): Add new CAIRO_STATUS_NULL_POINTER.
	This can be returned only if the user passes a NULL object in to a
	cairo function.

	* src/cairoint.h: Move include of <X11/extensions/Xrender.h> from
	cairo.h to here.

	* src/Makefile.am (libcairo_la_SOURCES): Add
	cairo_image_surface.c. Reformat line continuation characters.

	* src/cairoint.h: Remove prototypes for obsolete functions:
	_cairo_gstate_set_visual and _cairo_gstate_set_format.

2003-10-30  Carl Worth  <cworth@isi.edu>

	* src/cairo_xlib_surface.c (_cairo_xlib_surface_destroy): Fix
	memory leaks of surface->gc and surface->ximage.
	(_cairo_xlib_surface_composite):
	(_cairo_xlib_surface_composite_trapezoids): Fix memory leaks of
	cloned surfaces.

2003-10-30  Carl Worth  <cworth@isi.edu>

	* configure.in (CAIRO_VERSION): Bumped version to 0.1.9 for change
	in argument list of cairo_ft_font_create.

	* src/cairo_ft_font.c: A set of changes to eliminate the static
	FT_Library field, (which could introduce nasty problems with
	respect to threading). With the new code, each font created with
	the toy API will own its own FT_Library. Meanwhile,
	cairo_ft_font_create now accepts an FT_Library parameter.

	* src/cairo_ft_font.c: Add ft_library field so that fonts that own
	their own FT_Library can also clean it up.  Eliminate static
	FT_Library and _init_cairo_ft_lib.
	(cairo_ft_font_create): Now accepts an FT_Library argument.
	(_cairo_ft_font_create): Create an FT_Library owned by this font,
	(this only happens as part of the "toy API")
	(_cairo_ft_font_destroy): Clean up ft_font->ft_library if
	necessary.
	(cairo_ft_font_create_for_ft_face): Initialize ft_library and
	owns_ft_library.

	* src/cairo.h: Add FT_Library parameter to cairo_ft_font_create.

	* src/cairo_surface.c (_cairo_surface_create_similar_solid): Now
	that this function is internal, it can accept a cairo_color_t
	which makes the interface much cleaner.

	* src/cairo.h: Remove problematic function
	cairo_surface_create_similar_solid from the public API.

	for the reminder).

2003-10-09  Carl Worth  <cworth@isi.edu>

	* src/cairo_font.c: Stub out NULL_POINTER errors as
	CAIRO_STATUS_SUCCESS so that drawing to off-screen images still

	exposed cairo_path_t and related functions.

	* src/cairo_path.c (cairo_path_create):
	(_cairo_path_copy):
	(cairo_path_destroy): New create/copy/destroy functions for paths.

	cairo_x11_surface_put_image.
	(_cairo_surface_pull_image):
	(_cairo_surface_push_image): First real implementation of
	push/pull_image, (thanks for help from Graydon Hoare
	<graydon@redhat.com>). This provides support for running Cairo on
	X servers that do not have the RENDER extension. (Note: This is
	still woefully slow).

	* src/cairo_path_stroke.c (_cairo_stroker_join): Switch to
	_cairo_fixed functions.

	* src/cairo_path_bounds.c (_cairo_path_bounds): Use cairo_fixed
	rather than X macros.

	* src/cairo_gstate.c (_cairo_gstate_current_point): If not
	explicitly set, current point is (0,0) in user space.
	(_cairo_gstate_show_text): Fix to place text at user-space origin
	if there is no current point.

	(_cairo_gstate_fill): Now must ensure that gstate->source has been
	created.

	* src/cairo.c (cairo_set_target_surface):
	(cairo_set_target_drawable):
	(cairo_set_target_image): These functions can now clear
	status==CAIRO_STATUS_NO_TARGET_SURFACE. This is a clean solution
	to the bug of a SEGV if cairo_stroke/cairo_fill are called before
	cairo_set_target.

	* BUGS: Removed two fixed bugs, (SEGV if cairo_set_rgb_color
	called before cairo_set_target and SEGV if cairo_fill called
	before cairo_set_rgb_color)

2003-09-04  Keith Packard  <keithp@keithp.com>

	* src/cairo_path_stroke.c: added comments describing miter
	join code and miter limit computation.  Replace XFoo with cairo_foo
	for double and fixed

	* src/cairoint.h: add cairo_fixed_to_double and cairo_double_to_fixed
	Carl says he's got similar code, so he'll have to fix things if I
	get this committed quickly enough.

	* util/cairo-api-update: Added script to update source code using
	Cairo to the latest API.

	* configure.in (CAIRO_VERSION): Bumped version to 0.1.1

	* src/cairoint.h (DEPRECATE): Added magic DEPRECATE macro which
	provides an asm-based alias for old function names. This works on
	ELF systems with gcc version >= 2.

	* src/cairo.h (cairo_get_status_string): Deprecated all
	cairo_get_* names in favor of cairo_current_*. The deprecated
	function names will trigger either a warning or a link error, but
	in both cases with a useful message giving both the old and new
	name of the function. Three of the function name changes are
	different than the single word substituion:
		cairo_get_current_color	-> cairo_current_color
		cairo_get_status	-> cairo_status
		cairo_get_status_string	-> cairo_status_string
	
2003-09-03  Carl Worth  <cworth@east.isi.edu>

2003-08-28  Carl Worth  <cworth at east.isi.edu>

	* src/cairo_traps.c (_line_segs_intersect_ceil): One more
	increment, (that still won't fix the bug). Added comment point to
	Hobby's paper, (that will fix it).

	* src/cairo_font.c (_cairo_font_resolve_xft_font): Fixed to use
	fabs instead of abs when correcting for negative area expansion.

2003-08-28  Keith Packard <keithp@keithp.com
	* src/cairo_font.c: font pixel size is always non-negative

	theta in the pen. Instead, sort vertices by fixed point slope
	comparisons.
	(_cairo_pen_add_points): Fixed to remove duplicate pen vertices
	appearing at beginning and end of vertex array.
	(_pen_vertex_compare): New fixed-point "angle" comparison for pen
	vertices. A bit trickier than before, but much more accurate.

	* src/cairo_path_stroke.c (_cairo_stroker_face_clockwise): Share
	clockwise calculation with other modules.

	* src/cairo_path_bounds.c:
	* src/cairo_path_fill.c:
	* src/cairo_path_stroke.c:
	* src/cairo_pen.c:
	* src/cairo_polygon.c:
	* src/cairo_spline.c:
	* src/cairo_traps.c:
	* src/cairo_path.c: Replaced all references to
	XFixed, XPointFixed, XLineFixed, and XTrapezoid with new
	cairo_fixed_t, cairo_point_t, cairo_line_t, and cairo_trapezoid_t.

	* src/cairo_path.c: (_cairo_path_interpret): Made the path
	interpreter callback names consistent, (eg. add_edge rather than
	AddEdge).

	* src/cairo_gstate.c (_cairo_gstate_text_extents): Now silently
	exits for a non X surface, (avoids a crash until we can implement
	the libic text backend).

	* src/cairo_gstate.c (_cairo_gstate_end_group):
	(_cairo_gstate_clip_and_composite_trapezoids):
	(_cairo_gstate_show_surface): Replaced all XcCalls with
	corresponding cairo_surface_calls.

	* src/cairo_gstate.c (_cairo_gstate_transform_point):
	(_cairo_gstate_transform_font):
	(_cairo_gstate_text_extents): Renamed from the garbled names
	(eg. cairo_gstateransform_point) leftover from the great renaming.

	* src/cairo_color.c (_cairo_color_set_rgb): Reworked cairo_color_t
	to eliminate reference to an XcColor object.

	* src/cairo.h: Dropped include of <Xc.h>, added
	<X11/extensions/Xrender.h>, <fontconfig/fontconfig.h>, and <ic.h>

	* src/cairo.c (cairo_get_fill_rule): Added missing cairo_get_fill_rule.

	* configure.in (PKG_CHECK_MODULES): Drops xc, add libic

	* cairo.pc.in (Requires): Drop xc, add libic.

2003-07-25  Carl Worth  <cworth@isi.edu>

	* src/cairo_traps.c (_line_segs_intersect_ceil): We don't need a
	loop here, (just a conditional increment). This time, we've
	actually done the error analysis to back this up.

2003-07-24  Carl Worth  <cworth@isi.edu>

	* src/cairo_traps.c (cairo_traps_tessellate_polygon): Massive
	cleanup of polygon tessellation, (it might actually be correct
	now).

2003-07-23  Carl Worth  <cworth@isi.edu>

	* src/cairoint.h: Introduced some cairo_fixed_*_t types. This is
	the first baby step toward ripping X dependencies out of the Cairo
	headers.

	* src/cairo_traps.c (_compute_x): Converted from floating point to
	fixed point.
	(_line_seg_intersection_ceil): Now increments y value once if the
	initial y value computed is less than the actual intersection
	point.

	* src/cairo_traps.c (_compare_cairo_edge_by_slope): Converted from
	floating point to fixed point.

	* src/cairo_pen.c (_slope_clockwise): Converted from floating
	point to fixed point.

2003-07-19  Carl Worth  <cworth@isi.edu>

	* src/cairo_traps.c (cairo_traps_tessellate_polygon): Fixed some
	sorting problems with two intersections very near the same
	vertical position. (There are still some reamining problems
	though).
	(cairo_traps_tessellate_polygon): Better fix for the same
	bug. Should cover all cases, (and it's moe efficient too).

2003-07-18  Carl Worth  <cworth@east.isi.edu>

	* src/cairo.h: Fixed some inconsistent tag/typedef names that were
	missed in the great renaming.

2003-07-18  Carl Worth  <cworth@isi.edu>

	* src/cairo.h: Renamed everything from Xr* to cairo_*.

	* util/xr2cairo: Added utility script xr2cairo to help users fix
	their source code.

2003-07-03  Carl Worth  <cworth@isi.edu>

	* src/xrmatrix.c (XrMatrixGetAffine): Added XrMatrixGetAffine
	(from Soorya Kuloor)

	* src/xr.c (XrGetAlpha): Added XrGetAlpha
	(XrGetRGBColor): Added XrGetRGBColor

2003-06-12  Carl Worth  <cworth@isi.edu>

	* src/xrgstate.c (_XrGStateScale): Scale by 0 now causes an
	InvalidMatrix error.

2003-05-28  Carl Worth  <cworth@isi.edu>

	* src/xrmatrix.c (XrMatrixMultiply): Eliminated
	_XrMatrixMultiplyIntoRight and _XrMatrixMultiplyIntoLeft.

	* src/xrgstate.c (_XrGStateClipAndCompositeTrapezoids): Fixed
	missing translation of clip surface.

	* src/Xr.h: Added XrSurfacePutImage

2003-05-16  Carl Worth  <cworth@isi.edu>

	* src/xrint.h: Added ppm filed (pixels per meter) to both
	XrSurface and XrGState.

	* src/xrgstate.c (_XrGStateSetTargetSurface): Fixup CTM according
	to change in surface->ppm.
	(_XrGStateDefaultMatrix): Default matrix is no longer an identity
	matrix, but rather a matrix that provides some relates user space
	units to real-world dimensions in a meaningful way, (default 3780
	user space units per meter). This conversion is not exact, but is
	rather as close as possible while also guaranteeing that one user
	space unit maps to an integer number of device pixels.

2003-05-15  Carl Worth  <cworth@isi.edu>

	* src/xr.c (XrSetTargetDrawable): Moved implementation up from
	_XrGStateSetTargetDrawable, (eg. all convenience functions should
	be taken care of at the xr.c level ratehr than xrgstate.c)

	* src/Xr.h: Added convenience function XrSetTargetImage

2003-05-14  Carl Worth  <cworth@isi.edu>

	* src/xrfont.c (_XrFontResolveXftFont): Fixed fonts to pull
	pixelsize out of the transformation matrix. Fonts are now properly
	hinted regardless of scaling.

	* src/Xr.h: Three new functions for manipulating surfaces:
	XrSurfaceSetMatrix, XrSurfaceGetMatrix, XrSurfaceSetFilter.

	* src/Xr.h: Removed broken XrShowImage* functions. Changed
	XrShowSurface to not require X/Y but instead depend on the CTM for
	translation, (or the surface transformation matrix). I'd like to
	get rid of width/height as well but it turns out an XrSurface is
	not aware of its dimensions.

	* src/Xr.h: Added convenience function for building rectangular
	paths: XrRectangle.

	* src/Xr.h: Added functions for performing transformations with
	the CTM and its inverse: XrTransformPoint, XrTransformDistance,
	XrInverseTransformPoint, XrInverseTransformDistance.

	* src/Xr.h: XrConcatMatrix and XrSetMatrix now accept a pointer to
	an XrMatrix rather than 6 doubles.

	* src/Xr.h: Now exporting opaque XrMatrix object with several
	functions: XrMatrixCreate, XrMatrixDestroy, XrMatrixCopy,
	XrMatrixSetIdentity, XrMatrixSetAffine, XrMatrixTranslate,
	XrMatrixScale, XrMatrixRotate, XrMatrixInvert, XrMatrixMultiply,
	XrMatrixTransformDistance, XrMatrixTransformPoint.

2003-05-12  Carl Worth  <cworth@isi.edu>

	* src/Xr.h: Added XrSetPattern. See also XrSurfaceSetRepeat.

	* src/xrpathbounds.c (_XrPathBounds): Moved path bound computation
	to its own file.

	* src/xrpathstroke.c (_XrPathStrokeToTraps): Moved path stroking
	to its own file.
	
	* src/xrpathfill.c (_XrPathFillToTraps): Moved path fililng to its
	own file.

	* src/xrgstate.c (_XrGStateStroke):
	(_XrGStateFill):
	(_XrGStateClipAndCompositeTrapezoids): Reorganized stroke and fill
	code to go through the same path for clipping.
	
2003-05-02  Carl Worth  <cworth@east.isi.edu>

	* src/Xr.h: Changed XrFormatRGB32 to XrFormatRGB24

	* src/xrsurface.c (_XrFormatBPP, XrSurfaceCreateForImage)
	(_XrFormatDepth): Fixed for change of XrFormatRGB32 to
	XrFormatRGB24

2003-05-01  Carl Worth  <cworth@isi.edu>

	* src/xrpath.c (_XrPathBounderInit):
	(_XrPathBounderDeinit):
	(_XrPathBounderAddPoint):
	(_XrPathBounderAddEdge):
	(_XrPathBounderAddSpline):
	(_XrPathBounderDoneSubPath):
	(_XrPathBounderDonePath):
	(_XrPathBounds): New support for computing the bounding box of a
	path. Currently used internally, (for computing the size of the
	clip surface), and not exported publically.
	
	* src/xrgstate.c (_XrGStateStroke): Implemented clip support for
	strokes.
	(_XrGStateClip): New _XrGStateClip function fills the current path
	onto the gstate->clip surface.

	* src/xr.c (XrClip): Added preliminary/experimental clip
	functionality. The current implementation only clips stroked
	elements, (not fills, images, or text). It's alway quite
	inefficeient.

	* src/xr.c (XrGetOperator): 
	(XrGetTolerance): 
	(XrGetLineWidth): 
	(XrGetLineCap): 
	(XrGetLineJoin): 
	(XrGetMiterLimit): 
	(XrGetCurrentPoint): Added several new query functions.

2003-04-26  Carl Worth  <cworth@isi.edu>

	* src/xrsurface.c (XrSurfaceDestroy): Fix memory leak of
	surface->image_data.

2003-04-25  Carl Worth  <cworth@east.isi.edu>

	* configure.in: Fixed libtool versioning

2003-04-17  Carl Worth  <cworth@isi.edu>

	* Switched from imake to autotools.

	* src/xrint.h: XrSurface structure is now greatly simplified,
	(details now handled by XcSurface).

	* src/Xr.h: Eliminated Display * parameter so Xr can be used for
	non-X drawing.
	Removed XrPushGroup/XrPopGroup.
	Replaced XrSetDrawable/XrSetVisual with XrSetTargetDrawable.
	Added XrSetTargetSurface and several new XrSurfaceCreate
	functions.	
	Added XrShowSurface, (functionality overlaps with XrShowImage --
	need to fix this)
	

2003-02-14  Carl Worth  <cworth@east.isi.edu>

	* xrgstate.c (_XrGStateShowImageTransform): Fixed transformed
	images which were sometimes 1 pixel too tall/wide.

2003-02-06  Carl Worth  <cworth@isi.edu>

	* xrpen.c (_XrPenVerticesNeeded): Fixed to use determinant rather
	than eigenvalues to compute maximal scaling of radius. Now avoids
	embarrassing segfaults due to NaN from the eigenvalue computation.

2003-01-28  Carl Worth  <cworth@isi.edu>

	* xrtraps.c (_XrTrapsTessellateTriangle): Fixed to not re-order
	the array provided as an argument. (Note: the rectangle and
	polyghon tessellators still perform reordering).

	* xrstroker.c (_XrStrokerJoin):
	(_XrStrokerCap): Implemented round caps and joins.
	(_XrStrokerDoneSubPath): Fixed initial cap, (was always being
	drawn on the inside previously).

	* xrpen.c (_XrPenInit): Fixed to keep pen vertex theta values all
	in device space.
	(_XrPenAddPoints): Removed the silly flags from the pen vertices,
	(in favor of just using the FindActiveVertex functions)
	(_XrPenFindActiveCWVertexIndex):
	(_XrPenFindActiveCCWVertexIndex): Added functions needed for round
	caps/joins.

	* xrgstate.c (_XrGStateSetDash): Fixed to accept a NULL dash array
	to revert to no dashing.

2003-01-28  Carl Worth  <cworth@east.isi.edu>

	* xrtraps.c (_XrTrapsTessellateTriangle): Restored triangle
	tessellation functionality, (I think it's correct this time).

	* xrstroker.c (_XrStrokerJoin): Bevel joins now use triangle
	tessellation rather than polygon tessellation.

2003-01-24  Carl Worth  <cworth@east.isi.edu>

	* xrpolygon.c (_XrPolygonAddEdge): Fixed to handle multiple
	sub-polygons.

	* xrstroker.c (_XrStrokerJoin): Fixed handling of miter limit.

	* local.def: Added local.def for building outside the xc tree.

2002-12-03  Carl Worth  <cworth@isi.edu>

	* xrstroker.c (_XrStrokerJoin):
	(_XrStrokerCap): Fixed to track change in winding rule parameter
	to XrTrapsTessellatePolygon, (otherwise self-intersecting splines
	suddenly had holes).

	* xrpen.c (_XrPenStrokeSpline): Fixed to track change in winding
	rule parameter to XrTrapsTessellatePolygon.

2002-11-11  Carl Worth  <cworth@isi.edu>

	* xrtransform.c (_XrTransformBoundingBox): Added support for
	transforming a bounding box, (an axis-aligned rectangle prior to
	transformation). The ShowImage support needs this.
	(_XrTransformComputeInverse): Now catches error case for
	non-invertible matrix.

	* xrsurface.c (_XrSurfaceSetTransform): Fixed ordering of matrix
	for call to RenderSetPictureTransform

	* xrgstate.c (_XrGStateSetMatrix): 
	(_XrGStateIdentityMatrix): Support for new Xr matrix functions.
	(_XrGStateShowImage): 
	(_XrGStateShowImageTransform): Fixed transformation of images.

	* xr.c (XrSetMatrix): 
	(XrDefaultMatrix): 
	(XrIdentityMatrix): Added 3 matrix manipulation functions.

2002-11-04  Carl Worth  <cworth@isi.edu>

	* xrsurface.c (_XrSurfaceDereference):
	(_XrSurfaceDereferenceDestroy): Fixed bug in reference counting
	logic.
	(_XrSurfaceSetDrawableWH): XrSurface now keeps track of its width/height.
	(_XrSurfaceGetDrawable): 
	(_XrSurfaceGetWidth): 
	(_XrSurfaceGetHeight): 
	(_XrSurfaceGetDepth): New accessor functions.

	* xrgstate.c (_XrGStateBeginGroup):
	(_XrGStateEndGroup): Preliminary group support. Not too efficient
	since it always composite's a full-size picture from child group
	to parent picture, (even if only a small portion has
	non-transparent pixels).
	(_XrGStateShowImageTransform): Fixed show image to use current
	alpha value.

	* xrfont.c (_XrFontResolveXftFont): Fixed memory leak
	(FcPatternDestroy). There's still some meory
	leaking/left-reachable in Xft/fontconfig that I need to track
	down.

	* xr.c (XrPushGroup):
	(XrPopGroup): Added preliminary group support. I think I like
	having this in the API as it takes several burdens away from the
	user, (plus it matches the PDF model). Things to do still: think
	about the names of these functions. Re-read the PDF semantics to
	see if we're missing anything.

2002-11-02  Carl Worth  <cworth@isi.edu>

	* xrsurface.c (_XrSurfaceSetImage): Fixed leak of the image
	pixmap.

2002-11-01  Carl Worth  <cworth@east.isi.edu>

	* xrsurface.c (_XrSurfaceSetImage): Prelimary image
	support. Really only works with ARGB32. I still need to think
	about what formats will be supported.
	(_XrSurfaceSetTransform): Partial support for transformed
	surfaces.
	(_XrSurfaceGetXcSurface): Moved all creation/destruction of the
	XcSurface into this function so that it is only lazily created
	when needed.

	* xrgstate.c (_XrGStateSetCurrentPt): gstate now can throw errors
	when an operation needs current point, but it doesn't exist yet.
	(_XrGStateShowImage, _XrGStateShowImageTransform): Preliminary
	image support, (currently it only scales according to the CTM. The
	matrix passed with the image doesn't do anything yet.)

	* xrfont.c (_XrFontInitCopy): Removed bogus out of memory errors.

	* xr.c (XrShowImage, XrShowImageTransform): Added very preliminary
	image support. Things don't work completely yet and all the
	interfaces are likely to change.
	(XrGetStatusString): Added function to map status values to strings.

2002-10-31  Carl Worth  <cworth@isi.edu>

	* xrfont.c (_XrFontInit):
	(_XrFontInitCopy):
	(_XrFontDeinit):
	(_XrFontSelect):
	(_XrFontResolveXftFont): Updated by ripping all font support from
	Xc and just putting a couple of calls to Xft and fontconfig right
	here in xrfont.

	* xr.c (XrTextExtents): Added XrTextExtents.

2002-10-29  Carl Worth  <cworth@east.isi.edu>

	* xrgstate.c (_XrGStateSelectFont, _XrGStateScaleFont)
	(_XrGStateTransformFont, _XrGStateShowText): Added basic font
	support.

	* xr.c (XrSelectFont, XrScaleFont, XrTransformFont): Added basic
	font support.

2002-10-28  Carl Worth  <cworth@east.isi.edu>

	* xrstate.c (_XrStatePop): Added error case for XrRestore without
	matching XrSave.

	* xrsurface.c (_XrSurfaceInit, _XrSurfaceReference)
	(_XrSurfaceDereference): Added reference counting to XrSurface to
	patch a memory leak.

2002-10-26  Carl Worth  <cworth@isi.edu>

	* xrtransform.c (_XrTransformDistance):
	(_XrTransformPoint): changed to use individual X/Y arguments
	rather tha an XPointDouble. This improves readability since
	_XrTransformDistance is now always called with arguments of dx/dy
	rather than pt.x/pt.y.

	* xrpath.c (_XrPathMoveTo):
	(_XrPathLineTo):
	(_XrPathCurveTo):
	(_XrPathClosePath): replaced public _XrPathAdd with explicit named
	functions. This cleans up the implementation since _XrPathAdd,
	which is unsafe with respect to argument consistency, is now
	private. Also, since the _XrGState now maintains the current
	point, I dropped all relative path operators from the XrPath data
	structures.

	* xrgstate.c (_XrGStateMoveTo):
	(_XrGStateLineTo):
	(_XrGStateCurveTo):
	(_XrGStateRelMoveTo):
	(_XrGStateRelLineTo):
	(_XrGStateRelCurveTo): Replaces _XrGStateAddPathOp and
	_XrGStateAddUnaryPathOp with explicit named functions for each
	operator type. This change introduces the current point state into
	the XrGState structure rather than postponing its calculation
	until path interpretation.

	* xrgstate.c (_XrGStateSetDrawable):
	(_XrGStateSetVisual):
	(_XrGStateSetFormat):
	(_XrGStateSetOperator):
	(_XrGStateSetRGBColor):
	(_XrGStateSetTolerance):
	(_XrGStateSetAlpha):
	(_XrGStateSetFillRule):
	(_XrGStateSetLineWidth):
	(_XrGStateSetLineCap):
	(_XrGStateSetLineJoin):
	(_XrGStateSetMiterLimit):
	(_XrGStateTranslate):
	(_XrGStateScale):
	(_XrGStateRotate):
	(_XrGStateConcatMatrix):
	(_XrGStateNewPath): : Added XrStatus return values to many
	functions -- just for consistency, these functions can not return
	errors in any case.

	* xr.c (XrShowText): Started to ass XrShowText, (still not functional)

2002-10-24  Carl Worth  <cworth@isi.edu>

	* xr.c (XrSetFillRule): Added support to set fill rule.

2002-10-23  Carl Worth  <cworth@isi.edu>

	* xrtraps.c (_XrTrapsTessellatePolygon): Fix for polygon with
	multiple sub-polygons that are disjoint in Y.

2002-07-16  Carl Worth  <cworth@isi.edu>

	* Xr.h: Renamed xrpicture.c to xrsurface.c as part of the move.
	Added XrSetFormat, XrSetOperator, XrSetLineCap, XrSetLineJoin, and
	XrSetMiterLimit, (although the line style drawing code is not all
	in place yet).

	* xrpath.c (XrPathLineTo): Changed LineTo semantics to be the same
	as MoveTo if there was no previous MoveTo.

	* xrtraps.c: Added tessellation code, (lifted from
	XRenderCompositeDoublePoly which can now disappear).

	* xrgstate.c: Changed stroke code to incrementally build a list of
	trapezoids rather than forming one giant polygonal outline and
	rendering that. This should be more efficient.
	(_XrGStateFillPath): Now uses Xr's own tessellation along with
	XcCompositeTrapezoids.

	* Xr.h: Moved all of Xr away from Xrender to the new Xc library.

	* xrsurface.c: Renamed from xrpicture.c, (part of the move from
	XRender to Xc).

	* Started keeping a ChangeLog ;-)
