Might want to use something like CGToScalar here, though this is actually
CGToFloat (CGFloat is almost always double these days).

+    glyph->fAdvanceY = -cgAdvance.height;
 
     // The following produces skBounds in SkGlyph units (pixels, y down),
     // or returns early if skBounds would be empty.
