The fact that the Freetype background renderer draws a bounding box
around the entire region (as opposed to the actual text) is exactly
what prompted this patch.

That said, I should probably rig it up to disable the Freetype
background code for the CC decoder, in case the user has the
background opacity set to a non-zero value.
