Check for FT_GlyphSlot_Embolden()
Call FT_GlyphSlot_Embolden for fonts where FC_EMBOLDEN is set but that aren't bold. Add another private flag for this.
Use _cairo_fixed_to_double and _cairo_double_to_fixed when converting between double and 16.16 fixed point. These functions round nicely, and solve some inconsistencies in rendering between my PPC and x86 machines. Thanks to Owen Taylor for suggesting the fix.
The above change does affect linear gradients slightly, but it seems worth it. Update the reference images to follow.
Use pointer comparison for coincident points to ensure a well-defined ordering, and avoid setting discard on both points. This fixes problems with my Mac's implementation of qsort. Final patch by Bertram Felgenhauer.
Update reference images after the change.
Improve the performance of png reading by adding special cases for fully transparent and fully opaque alpha, and using the standard optimization for 8-bit division by 255.
Add an INLINE macro for gcc.
Don't change the status value if it already holds an error. This avoids destroying "first error" information and also avoids attempting to write read-only data, (eg. from nil objects).
Don't set an error on the same object if it is in an error state to begin with, just return immediately. This is intended to reduce (eventual) error prints to the first cause of an error for any given object, instead of a continual spew.
Adjust negative offsets up to their equivalent positive value. Add error checking for dash values, (must each be non-negative and must not be all zero).
Add documentation.
Add new CAIRO_STATUS_INVALID_DASH.
Add dash-offfset-negative test from Owen.
churn
New function to return the current nil pattern depending on the status.
Add missing early bailout on surface->status with error propagation to the pattern.
Related cleanups for cairo_pattern_t:
Don't check other->status since this is a static function.
Add missing early bailout on other->status.
Cleanup identifier names.
Track rename of nil patterns.
Don't call _cairo_error for pre-existing errors.
Take care to initialize some fields to that _cairo_pattern_release_surface will work even after an error.
Track rename of cairo_solid_pattern_nil to cairo_pattern_nil.
New test to ensure that a file-not-found error will propagate from a surface, through a pattern, and onto a cairo_t.
CLEAR and SOURCE are now bounded.
Assert that SOURCE and CLEAR aren't passed to these functions.
Assert that SOURCE and CLEAR aren't passed to these functions when there is a mask.
Do fixups for SOURCE and CLEAR as well as unbounded operators, since in the absence of a mask, we need SOURCE to work correctly (don't care about CLEAR)
_cairo_ft_font_show_glyphs) Consistently use CLEAR/TRANSPARENT (source doesn't matter) rather than SOURCE/TRANSPARENT when clearing rectangles.
src/cairo-xlib-surface.c src/cairo-surface.c: Use IN rather than SOURCE as an example of an unbounded operator in docs.
Remove CLEAR/SOURCE columns since they are no longer unbounded.
test/operator-clear.c test/operator-source Makefile.am: Add targetted tests of CLEAR/SOURCE.
Don't call _cairo_ft_unscaled_font_init_key in the from_face case, just clear filename and id instead. Initialize unscaled->base first so that initialization order matches the structure declaration order.
Fix to accept a NULL string and hash it identically to a zero-length string.
Add a test that calls cairo_ft_font_create_for_ft_face to demonstrate bug #4110.
src/cairo-clip.c src/cairo-gstate.c: Use them.
Move code to fill a pixman_region16_t to here.
Document.
Use _cairo_surface_fill_region().
Add a return status, use regions to simplify.
src/cairoint.h
Handle the return value from _cairo_surface_composite_fixup_unbounded().
src/cairo-surface.c src/cairoint.h (_cairo_surface_composite_shape_fixup_unbounded): Add a variant of _cairo_surface_composite_fixup_unbounded() to avoid creating a dummy cairo_surface_attributes_t.
Use _cairo_surface_composite_shape_fixup_unbounded().
Call _cairo_surface_composite_shape_fixup_unbounded(), since the source might still be restricted, even though the mask is unbounded.
Restore the rectangle optizations when drawing with unbounded operators by adding a clear for the extra area after drawing the rectangles.
Document cairo_pattern_add_color_stop_rgb, cairo_pattern_add_color_stop_rgba, cairo_pattern_set_matrix, and cairo_pattern_get_matrix.
Add note on user-space locking to the documentation for cairo_set_source().
Setup an automake conditional for the HAVE_PTHREAD case.
Link all tests with -lpthread if available, so that we can get some testing of cairo with mutexes turned on.
Convert the font_face/matrix/ctm/options => cairo_scaled_font_t mapping from a two-layer cairo-cache.c implementation to a single cairo-hash.c implementation backed by a simple array for the secondary cache.

Complete the remainder of the simple -> toy renaming. Convert the family/slant/weight -> cairo_toy_font_face_t mapping to use cairo-hash.c rather than cairo-cache.c.
Remove const qualifier from toy_face parameter to creat_toy, as these functions may reference the font face. Track addition of font_face parameter to _cairo_scaled_font_init.
Implement font_face parameter to _cairo_scaled_font_init, moving the reference of the font_face from _cairo_inner_font_cache_create_entry.
Add a font_face parameter in addition to the unscaled_font parameter.
Track new font_face parameter to _cairo_ft_scaled_font_create.
Whitespace touchup.

Build pixman internally as a private part of cairo, with suitable name changes to avoid any visible pixman symbols in the cairo library:
Descend into pixman.
Drop libpixman from Requires.
Don't check for libpixman. Check version of pkg-config and use Requires.private instead of Requires in cairo.pc if possible. Generate pixman Makefiles.
Rip out release-publish target and installation of libpixman.pc.
Add pixman-remap.h. Drop libpixman.la target.
Fix to include config.h rather than ../config.h
This is the cpp magic to rename all pixman functions from the various fb, Fb, INT_pixman, pixman, Render, _Render, or no prefix to _cairo_pixman_ prefixes.
Include pixman-remap.h to get all the cairo-internalized names.
Add -Ipixman/src to get at pixman-remap.h.
Update to use AC_INIT and AM_INIT_AUTOMAKE in recommended ways. Add support for substituting CAIRO_VERSION_MAJOR/MINOR/MICRO into generated headers.
Add CAIRO_VERSION_MAJOR/MINOR/MICRO and CAIRO_VERSION_STRING which are generated by configure.
