Fix missing rounding in these two functions.
Update these to versions with properly rounded alpha values.
Move clip_twice out of XFAIL now that rounding works.
Add new test cases.
src/cairo.[ch] src/cairo-matrix.c: Add some inline docs for arcs and matrices.
gtk-doc.m4 acinclude.m4: Check in files from gtk-doc to make the dependency on gtk-doc optional.
Add --enable-gtk-doc to the default args.
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.
Change these functions to not create a surface for the pattern and just pass the pattern down to the backend functions.
New function to translate a set of trapezoids.
Break out the code to adjust and restore surface transformation and repeat settings into _cairo_pattern_prepare_surface and _cairo_pattern_restore_surface.
Split cairo_pattern_create_for_surface into an init function and a create function.
Utility functions to create a surface from a pattern.
Update these backends to work with the new pattern API. Glitz work by David Reveman.
Update these to pass through the new set of args.
Update this reference image as we now render it correctly.
Add new testsvg script and accompanying imagediff program, (for interim SVG-based test suites while we wait for the standard cairo test suite to mature).
Split buffer_diff out into its own file for the purpose of imagediff.
src/cairoint.h src/cairo_font.c src/cairo_ft_font.c src/cairo_xlib_surface.c src/cairo_pdf_surface.c src/cairo_gstate.c src/cairo.c: Switch many internal methods from handling cairo_unscaled_font_t and cairo_font_scale_t pairs to handling cairo_font_t.
src/cairo-ft-private.h src/cairo_ft_fontc: Add some internal interfaces for use by the FreeType backend.
Clear the gstate's current font when the transform or target surface changes.
src/cairo.h src/cairo_ft_font.c: Rename cairo_ft_font_pattern to cairo_ft_font_get_pattern().
src/cairo.h src/cairo_ft_font.c: Make cairo_ft_font_create() and cairo_ft_font_create_for_ft_face() take a font scale; make the latter take load_flags for FT_Load_Glyph() as well. Change cairo_ft_font_face() to Xft-style cairo_ft_font_lock_face, cairo_ft_font_unlock_face.
Remove the name/slant/weight=>unscaled font cache, it didn't work with the new cairo_font_t setup. If it turns out to be needed, it can be added back in some other form.
src/cairoint.h src/cairo_font.c: Add a 'flags' field to cairo_glyph_cache_key_t, we use it for load flags with freetype backend.
Switch the caching to be from resolved fontconfig pattern => file; keep only a fixed number of FT_Face objects open at once, similar to FreeType.
src/cairo_gstate.c src/cairoint.h: Add public cairo_font_glyph_extents, use it to implement _cairo_gstate_glyph_extents().
Add refcounting for glyph cache elements; there was an bug where elements got ejected from the cache and freed before they could be used.
src/cairoint.h src/cairo_cache.c (_cairo_cache_random_entry()) New function to return a random entry in the cache matching a predicate; reuse the internals for the previous _random_live_entry().
src/cairoint.h src/cairo_cache.c (_cairo_cache_lookup()): Add an optional created_entry return value.
src/cairo_ft_font.c src/cairo_xlib_surface.c: Adapt to _cairo_cache_lookup() change.
Support max_memory == 0 to indicate an unbounded cache.
src/cairoint.h src/cairo_cache.c (_cairo_cache_remove()): Add a function to manually remove entries from the cache.
Update for changes, document cairo_matrix_t, cairo_glyph_t, etc.
src/cairo.h src/cairo-atsui.h src/cairo-ft.h src/cairo-glitz.h src/cairo-pdf.h src/cairo-png.h src/cairo-ps.h src/cairo-quartz.h src/cairo-xcb.h src/cairo-xlib.h: Add CAIRO_BEGIN/END_DECLS for extern "C", use it on all public headers. Move header guards outermost.
Fix encoding.
Replace IcRasterizeTrapezoid with fbRasterizeTrapezoid. Add a couple of missing typedefs.
Minor changes to allow things to compile within libpixman tree, (replace xserver include directives with pixman-xserver-compat.h and sprinkle a few const qualifiers).
Add sources for new point-sampling rasterization.
Build fixes for Quartz backend courtesy of Geoff Norton <gnorton@customerdna.com>:
Fix check for atsui font backend.
Add conditional compilation for cairo_atsui_font.c and cairo_ft_font.c.
Add missing include of cairo-quartz.h.
Add include of Carbon/Carbon.h.
Advertise availability of Quartz surface.
Install cairo-quartz.h, and conditionally compile cairo_quartz_surface.c.
Add autofoo checks to detect quartz backend.

Insert new includes for backend-specific header files.
Remove redundant include of cairo-features.h.
Rename header-exclusion macro from _CAIRO_H_ to CAIRO_H. Remove platform-specific grubbing for cairo-features.h and pixman.h in odd places.
Remove all backend-specific prototypes, (as they are now in their own header files).
Remove deprecated
Remove printf.
Convert to utf-8. Use the proper name for multiple-header exclusion (CAIRO_FEATURES_H). Track rename of FREETYPE_FONT_FEATURE to FT_FONT_FEATURE.
Split cairo.h up into cairo.h, cairo-ft.h, cairo-glitz.h, cairo-pdf.h, cairo-png.h, cairo-ps.h, cairo-xcb.h, cairo-xlib.h. Update for rename of cairo_wideint.h to cairo-wideint.h.
Rename CAIRO_HAS_FREETYPE_FONT to CAIRO_HAS_FT_FONT, (to match cairo_ft_font functions and cairo-ft.h).
Update for public header files now in /cairo.
Change type of 'surface' argument in show_glyphs to void * as it is for all other surface virtual functions.
Update accordingly.
Add check for endianess.
Fix bug in array growing loop. (_cairo_array_append): Accept NULL for elements argument, in which case we just allocate space in the array.
