New function to reset all static data (eg. caches) to their initial state.
Fix check-valgrind target to depend on the 'all' target.
Add check for a new, proposed, XrmFinalize function.

Implement reset_static_data in all modules as required.
Call cairo_debug_reset_static_data and FcFini so that we can have all tests be valgrind-clean with respect to memory leaks and still-reachable data.

Don't check for gstate->target == NULL anymore as the API now guarantees it never occurs.

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.
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()
Check the status of gstate->source and of mask patterns passed in.

Add a status field to cairo_path_t.
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.
Add missing cairo_private qualifier to a couple functions.
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.

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.
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.
Manage clip objects entirely within the gstate, loading the whole thing into the surface just before drawing.
Source surfaces need not have clipping modified as the surface interface now specifies that source surfaces are always unclipped.
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.
Region clipping capability is now signalled by a non-NULL function pointer in set_clip_region.
Each surface now contains two Pictures, one for source and one for destination operands so that source operands are never clipped by destination clipping.
CAIRO_STATUS_BAD_NESTING removed
self-copy now passes (Xlib only, until libpixman changes land)
