Tor Arne Vestbø 5a060a5ad3 CoreText: Prevent creation of CGContext for glyphs with empty bounding box 
If the alphaMapBoundingBox of a glyph is empty we don't want to create
a CGBitmapContext on it, as that will fail, and any further operations
on the invalid context will result in possibly fatal errors from CG.

This issue can be observed when drawing some glyphs of the Apple Color
Emoji font.
