smaller than the original, seems to work well down to about a scale
of 50%.
* clutter/pango/pangoclutter-fontmap.c:
(pango_clutter_font_map_default_substitute): turn off hinting.
* clutter/pango/pangoclutter-render.c: request linear filtering
instead of nearest neighbour when scaling down.
* tests/test-text.c: replaced test with a a test that renders a sample
grid with various pixel sizes and scales for visual inspection of
text rendering quality.
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c: Set the default resolution
as 96.0 dpi for every backend (we already were under this
assumption anyway, and this makes it easier to change this
setting per-backend).
* clutter/pango/pangoclutter-fontmap.c:
* clutter/pango/pangoclutter.h: Allow setting the resolution
for the PangoClutterFontMap object and provide the implementation
for the PangoFcFontMap::get_resolution() virtual function. This
allows to set the resolution of the PangoContext when retrieving
it.
* clutter/clutter-label.c (clutter_label_init): Set the
resolution of the font map with the one the backend gives us.
* clutter/clutter-entry.c (clutter_entry_init): Ditto.
