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.

Eliminate G_CONST_RETURN
The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy.
We always used it to conform to the platform, at least for public-facing
API.
At first I assumed it has something to do with brain-damaged compilers
or with weird platforms where const was not really supported; sadly,
it's something much, much worse: it's a define that can be toggled at
compile-time to remove const from the signature of public API. This is a
truly terrifying feature that I assume was added in the past century,
and whose inception clearly had something to do with massive doses of
absynthe and opium — because any other explanation would make the
existence of such a feature even worse than assuming drugs had anything
to do with it.
Anyway, and pleasing the gods, this dubious feature is being
removed/deprecated in GLib; see bug:
https://bugzilla.gnome.org/show_bug.cgi?id=644611
Before deprecation, though, we should just remove its usage from the
whole API. We should especially remove its usage from Cally's internals,
since there it never made sense in the first place.
