Fix positioning in GL2 paint engine with subpixel antialiasing
In this case we will use QTextureGlyphCache with FreeType renderer,
which requires the subpixel positition to get correct left bearings,
thus alphaMapBoundingBox is extended to support subPixelPosition.
In QFontEngineFT we also simplify the code a bit by reusing
loadGlyphs for metrics calculation instead of duplicate code. Since
we need to use the glyphs after all, cache them here in
alphaMapBoundingBox shouldn't be a problem.
