Freetype: Fix device pixel ratio with large fonts
When the dpr scale caused pixel sizes to reach 64 pixels and up, thus triggering the outline drawing fallback, we would render the glyphs at the original size but scale the glyph positions, giving broken rendering. This was because we did not actually pass the matrix to the fallback function when getting the alpha maps. Fixing it revealed a different problem, which was that the bounding box for the glyphs, returned by alphaMapBoundingBox() did not actually apply the transform when outline drawing was enabled. [ChangeLog][QtGui][Text] Fixed rendering of large fonts when a device pixel ratio is set and the Freetype engine is used.
