Add freetype flags so that things work with freetype in a non-standard location, (a little extra work here since freetype doesn't use pkg-config).
Add several items culled from recent mailing list discussions.
Add bugs on cache locking and surface pattern scaling.
Support tests that produce no output, (don't check image if (width,height) == (0,0)).
Add #include <assert.h> here rather than in multiple .c files.
Add const qualifier to static cache_arrangements table. (_cache_sane_state): Remove refcount assertion as it it false during the cairo_cache_destroy. (_cache_sane_state): #include <assert.h> moved up to cairoint.h (_entry_destroy): Fix bug in assertion (used_memory >= entry->memory), not >. (_cairo_cache_destroy): Fix timing of refcount decrement so that the destroy function actually works.
Don't AC_SUBST a dozen different FOO_CFLAGS and FOO_LIBS. Instead, incrementally build up just CAIRO_CFLAGS and CAIRO_LIBS.
Don't list flags that should get picked up via dependency information through Requires.
Add description of move_to_show_surface.
Explicitly add cases for all enum values to eliminate compiler warnings.
Remove proposal for surface_clip interface as cairo_clip should be able to cover this case now.
Added bug concerning negative ref_counts.
Added notes on DPI for image-based backends and on proposal for new cairo_text_glyphs function.
Added BUG about cairo_show_text not advancing the current point.
