I just thought I would add that the GetGlyphID function and several others
won't work for embedded fonts. That's pretty much it.
So, the approach I have been taking makes the assumption that these fonts
lie on my system when in fact the fonts are embedded.
I personally think knowing this requires a deeper understanding of podofo
the average user won't have. It might be worth putting that information
into the documentation. Just a suggestion.
We have spent some time on this now and have just realized the approach we
have been taking is all wrong.
