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.
