- Update to 3.0.1:
* Added fcft_font.name member for the name of the primary font.
* Added fcft_glyph.font_name member for the name of the font that the glyph
was loaded from.
* Added fcft_init and fcft_fini to initialize and deinitialize the library,
which must now be called explicitly. Also, fcft_log_init has been removed,
and logging is now initialized by fcft_init.
* All wchar_t usage has been replaced with uint32_t. Also,
fcft_{glyph,grapheme,text_run}_rasterize have been renamed to
fcft_rasterize_{char,grapheme,text_run}_utf32 to emphasize this.
* fcft_rasterize_grapheme_utf32 no longer accepts layout tags, unlike
its predecessor fcft_grapheme_rasterize. They should be
set using fontfeature when calling fcft_from_name.
* Removed fcft_size_adjust.
* Removed fcft_font.space_advance member.
* Fixed bug in fcft_rasterize_text_run_utf32 due to uninitialized variable.
