Refactor lockedAlphaMapForGlyph
Simply return a Glyph pointer and not a QImage to avoid allocating and
deleting lots of d pointers for QImage when drawing text. Saves one
new/delete pair per glyph drawn and speeds up text drawing by 10% for
relatively large glyphs (probably more for smaller ones).
The qtext::paintLayoutToPixmap() benchmark shows a 16% improvement
in performance with this change.
Renamed the method to glyphData().
