Gunnar Sletta 35bc3dc45a Rely solely on alphaMapBoundingBox in QTextureGlyphCache 
We're currently adding a lot of transparent pixels to the cache,
wasting both memory and cpu cycles while drawing. AlphaMapBoundingBox
was introduced to return the exact same bounds as the alphaMapForGlyph
function so we should only rely on this instead of adding arbitrary
padding and margins all over the place.

Windows still has an arbitrary +4 in the its drawGDIGlyph() which
means batching will not work on windows, but at least now
other platforms do not need to suffer.
