Bug #919 - Replacement pango renderer (Neil Roberts) * clutter/clutter-backend.h: * clutter/clutter-backend.c: (clutter_backend_set_font_options), (clutter_backend_get_font_options): Add the ability to set the cairo_font_options_t* for the backend at construction time, so that backend implementations can have their own options. * clutter/clutter-color.c: Include pango/pango-attributes.h for the pango_color_parse() function. * clutter/clutter-label.c: (clutter_label_ensure_layout), (clutter_label_init), (clutter_label_set_text), (clutter_label_set_font_name), (clutter_label_set_ellipsize), (clutter_label_set_use_markup): Ensure that the cache is always primed when the Label changes; this makes sure that the cache is rebuilt outside the paint run, which should make the painting perform better especially on embedded devices. * clutter/clutter-entry.c: (clutter_entry_ensure_layout), (clutter_entry_init), (clutter_entry_set_text), (clutter_entry_set_font_name): Ditto as above. * clutter/clutter-private.h: * clutter/clutter-main.[ch]: Create the font-map inside the main context; add two new functions: clutter_clear_glyph_cache() clutter_set_use_mipmapped_text() that control the glyphs cache. * clutter/pango/Makefile.am: * clutter/pango/pangoclutter-fontmap.c: * clutter/pango/pangoclutter-private.h: * clutter/pango/pangoclutter-render.c: * clutter/pango/pangoclutter.h: Rewrite the Pango renderer using a PangoCairo context and saving the glyphs inside a more efficient cache. * configure.ac: Depend on pangocairo instead of pangoft2.
