src/cairo-array.c src/cairoint.h src/cairo-surface.c: Refactor user data code from cairo-surface.c into cairo_user_data_array_t. Switch these types to be like cairo_surface_t where the generic code frees the wrapper object. src/cairo-atsui-font.c src/cairo-ft-font.c src/cairo-win32-font.c: Fix up for the above changes. Implement a complicated mutual-referencing scheme to make sure that a face from cairo_ft_font_face_create_for_ft_face() is freed only when the FT_Face is no longer needed. Update the docs to describe how to figure out when the FT_Face can be freed. Fix refcount leaks when creating fonts. Remove excess call to _cairo_unscaled_font_reference(). Remove stray initialization of font matrix to the identity. test/user-data.c: Fix a bug when setting/unsetting a key with a free key slot before it, add that to the test case. Don't append an element when user_data is NULL.
