Adjust distance field glyph and font atlas sizes to maximize storage.

Adjust distance field glyph and font atlas sizes to maximize storage.

Because of high DPI devices, we need more room in the glyph
atlas for the larger glyphs. These settings will allow 4 of 
the distance field glyphs to fit in one Plot (increasing
the storage from 32 large glyphs to 128), and still permit
us to handle glyphs up to a 312 point size.

Btw, once this change is in, I can turn on distance field text on Android. So
PTAL.

The reason for reverting is: There's some weirdness with Tegra2 and Tegra3 GMs
(Xoom and Nexus7) that may be related to this..
