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.
