Updated distance field glyph caches to use QDistanceField.
Some OpenGL drivers assume alpha-only images are always tightly packed,
regardless of what is set for GL_UNPACK_ALIGNMENT. We now use
QDistanceField to store glyphs, which aligns scanlines on a 1-byte
boundary, instead of QImage which uses a 4-byte boundary. A previous
workaround uploaded scanlines one at a time, but this is also broken
with some other drivers...
