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. Task-number: 249178 Reviewed-by: Samuel
