+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.

+ cairo_xlib_surface_create needs to be screen aware, and
+ cairo_xlib_surface_set_drawable).

+ is computing an incorrect result.
+
+2005-07-08 Carl Worth <cworth@cworth.org>

+Snapshot 0.5.2 (2005-07-18 Carl Worth <cworth@cworth.org>)
+==========================================================
+API changes
+-----------
+* New functions for creating patterns of a single color:
+
+ cairo_pattern_create_rgb
+ cairo_pattern_create_rgba
+
+* Change cairo_surface_create_similar to accept a new type of
+ cairo_content_t rather than cairo_format_t:

+ typedef enum _cairo_content {
+ CAIRO_CONTENT_COLOR = 0x1000,
+ CAIRO_CONTENT_ALPHA = 0x2000,
+ CAIRO_CONTENT_COLOR_ALPHA = 0x3000
+ } cairo_content_t;
+
+* Add new CAIRO_FORMAT_VALID and CAIRO_CONTENT_VALID macros.
+
+* Remove unused status value:
+
+ CAIRO_STATUS_NO_TARGET_SURFACE
+
+* Add new status values:
+
+ CAIRO_STATUS_INVALID_STATUS
+
+* Require libpixman >= 0.1.5 (for necessary bug fixes)
+
+Bug fixes
+---------
+* Fix cairo_surface_write_to_png for RGB24 images.
+
+* Fix broken metrics and rendering for bitmap fonts. Add mostly
+ useless bitmap glyph transformation.
+
+* Fix glyph caches to not eject entries that might be immediately
+ needed, (fixing intermittent crashes when rendering text).
+
+* Fix all memory leaks found by running "make check-valigrind".
+
+ATSUI backend changes
+---------------------
+* Allow building against < 10.3 SDK.
+
+* Prevent crash on empty strings.
+
+Glitz backend changes
+---------------------
+* Require glitz >= 0.4.4.
+
+* Use frame buffer objects instead of pbuffers for accelerated
+ offscreen drawing.
+
+* Minor improvement to gradient pattern creation.
+
+PostScript backend fixes
+------------------------
+* Rewrite of the PS backend to generate more interesting output that
+ the old big-image implementation.
+
+Win32 backend fixes
+-------------------
+* Implement glyph path support.
+
+* Fix swap of blue and green values in the fill_rectangles path.
+
+Xlib backend fixes
+------------------
+* Add optimization to use XCopyArea rather than XRenderComposite when
+ transforming only with an integer translation, and using SOURCE
+ operator or OVER with a source pattern without alpha.

-progress).
+cairo 0.5.2
+===========
+✓ Get tor to sign off that the win32 stuff is up to snuff
+ ✓ glyph path patch reviewed and committed
+
+✓ Fix the BadMatch error introduced between 0.5.0 and 0.5.1:
+ https://bugs.freedesktop.org/show_bug.cgi?id=3604
+
+ (It turns out this was just exposing an old bug in libpixman
+ 0.1.4 which is already fixed in libpixman 0.1.5)
+
+ Add a workaround for Render's overlapping source/dest bug
+ ✓ Use XCopyArea when possible (integer translation)
+ Otherwise make a copy of the source
+
+ Fix the cache lock deadlocking problems.
+ Difficulty: Hard
+ Status: The cache code was ugly enough that I ended up doing a
+ major rewrite rather than just reviewing the
+ locking. The upside is that the rewrite should also
+ add the missing metrics caches which will fix some
+ performance problems with text measurement. Almost
+ done now.

+ * be type-compatible with this structure (eg. they must have an
+ * unsigned long as the first parameter. The easiest way to get this
+ * is to use:
+ *
+ * typedef _my_entry {
+ * cairo_hash_entry_t base;
+ * ... Remainder of key and value fields here ..
+ * } my_entry_t;

+ * which then allows a pointer to my_entry_t to be passed to any of

+ *
+ * _cairo_hash_table_insert (hash_table, &my_entry->base);
+ *
+ * IMPORTANT: The caller is reponsible for initializing
+ * my_entry->base.hash with a hash code derived from the key. The
+ * essential property of the hash code is that keys_equal must never
+ * return TRUE for two keys that have different hashes. The best hash
+ * code will reduce the frequency of two keys with the same code for
+ * which keys_equal returns FALSE.
+ *
+ * Which parts of the entry make up the "key" and which part make up
+ * the value are entirely up to the caller, (as determined by the
+ * computation going into base.hash as well as the keys_equal
+ * function). A few of the cairo_hash_table functions accept an entry
+ * which will be used exclusively as a "key", (indicated by a
+ * parameter name of key). In these cases, the value-related fields of

* This table is open-addressed with double hashing. Each table size is a
* prime chosen to be a little more than double the high water mark for a
* given arrangement, so the tables should remain < 50% full. The table
* size makes for the "first" hash modulus; a second prime (2 less than the
* first prime) serves as the "second" hash modulus, which is co-prime and
* thus guarantees a complete permutation of table indices.

+ * file xserver/render/glyph.c in the freedesktop.org x server, with
+ * permission (and suggested modification of doubling sizes) by Keith
