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.

<simpara>A <link linkend="cairo_font_t">cairo_font_t</link> from the FreeType font backend. Such

an object can be created with <link linkend="cairo_ft_font_create">cairo_ft_font_create</link> or

<link linkend="cairo_ft_font_create_for_ft_face">cairo_ft_font_create_for_ft_face</link>. On some platforms the font

from <link linkend="cairo_current_font">cairo_current_font</link> will also be a FreeType font, but

|
using this functionality with fonts you don't create

yourself is not recommended.

<function>cairo_ft_font_get_pattern</function> gets the <structname>FcPattern</structname>
|
|
for a FreeType backend font. The return value is owned
|
|
by the font, so you must not modify it, and must call
|
|
<function>FcPatternReference</function> to keep a persistant
|
|
reference to the pattern. If the font was created with
|
|
<link linkend="cairo_ft_font_create_for_ft_face">cairo_ft_font_create_for_ft_face</link> the result will be NULL.
