Fixed an issue with text drawing to QImages on Mac/Cocoa.
We currently don't support subpixel hinting when drawing text to a
QImage on Mac. The alpha map that is returned by the font engine
is a plain 8 bit gray mask, which means we have to switch off subpixel
hinting when we draw the glyph for caching.
