Call error_notify callback if set. (cairo_create): Initialize error_notify callback to NULL. (cairo_set_error_notify): New function to allow the user to set an error notify callback.
New cairo_set_error_notify prototye.
New test for cairo_set_error_notify.
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)

Add cairo_xlib_surface_create_with_render_format.
Reduce Xlib constructors down to two simple forms. Add width, height to constructors and eliminate any synchronous size queries from the implementation.
Update to match new cairo_xlib_surface_t create functions.
Remove destroy_closure argument from cairo_pdf_surface_create_for_stream. Rename width,height to width_in_points, height_in_points for better clarity.
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.
Make it a little more clear that the width and height being passed around are in units of points.
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.
src/cairo-xlib-surface.c src/cairo-xlib-test.h Makefile.am: add cairo_test_xlib_disable_render() to turn off RENDER for tests.
Test various different types of Xlib surface creation.
Remove left-over include of Xrender.h.
Set fill type repeat on source surface. (_cairo_glitz_surface_show_glyphs): Add missing cairo operator to glitz operator conversion. (_cairo_glitz_surface_show_glyphs): Only render glyphs with non zero size.
Fix bounding box computation.

Also, eliminate all support for compiling against, or running with old, deprecated names for functions.
Deal with all of the removals.
Port to use new cairo_create interface.
Rewrite all tests that were using cairo_set_target_surface to instead create a temporary cairo_t, (eventually to be replaced with cairo_begin_group).
Fix segfault when mask == NULL.
test/mask.c test/mask-ref.png: Add testing of cairo_paint_with_alpha().
test/coverage.c test/coverage-ref.png: Remove ... it's not testing anything that mask doesn't test better.
Remove cairo_show_surface. Add new cairo_set_source_surface.
Remove _cairo_gstate_show_surface.
Replace calls to cairo_show_surface with cairo_set_source_surface; cairo_paint.
Fix messages to prefer - over _.
Fix documentation.
Three new tests to exercise set_source_surface more completely, (two of these are expected failures dues to outstanding bugs).
Add a CAIRO_STATUS_BAD_NESTING error for interleaved use of two cairo_t's on the same surface. Also, add a skeleton doc comment for cairo_status_t.
src/cairo.c src/cairo-gstate.c src/cairoint.h: Use _cairo_surface_begin/end to replace _cairo_gstate_restore_external_state.
Use _cairo_surface_begin/end to save the state of a surface when we start drawing at it and restore it at the end. Check that the save level of the surface is what we expect on drawing operations and fail with CAIRO_STATUS_BAD_NESTING otherwise.
src/cairo-pattern.c src/cairoint.h (_cairo_pattern_acquire_surface_for_surface) (_cairo_pattern_release_surface): Surround use of pattern->surface with _cairo_surface->begin/end so we don't clip surfaces used as sources.
test/clip-nesting.c test/Makefile.am: Test of destinatin clipping with the nested creation of cairo_t's for the same context.
test/source-clip.c test/Makefile.am: Test that clipping on a source as a destination doesn't affect use of it as a source.
XFAIL test for copying from a surface as a source to itself as a destination with a clip.
Add cairo_stroke_preserve, cairo_fill_preserve, and cairo_clip_preserve.
Rip the path out of cairo_gstate_t.
Add path to cairo_t.
Bring in most of the path code that used to live in cairo-gstate.c
Move arc generation code into its own file.
Accept path+ctm_inverse+tolerance instead of gstate. Absorb flattening and device space->user space conversion that used to be in _cairo_gstate_intepret_path.
Prefer cairo_fixed_t parameters over ciaro_point_t for cross-file interfaces.
Track changes in _cairo_path_fixed interfaces.
Port to use cairo_fill_preserve rather than cairo_save/cairo_restore which no longer work for saving the path.
Remove get and set of current point since it is no longer affected by cairo_save and cairo_restore. Add get and set testing for cairo_matrix_t.
Add new get_extents function to the surface backend interface.
Add function to query current clip_extents.
Implement the new get_extents function for each backend.
Save the clip extents from set_clip_region and implement _cairo_surface_get_clip_extents.
Abstract away the evil XGetGeometry roundtrip in _cairo_xlib_surface_get_size.
Rewrite a couple of tests to call cairo_paint.
