Hmm.  Since PDFs come with its own set of cmap files, there is a
certain redundancy...

In this particular case I think FreeType should do a default action;
this is, a missing `cmap' table should completely disable functions
like FT_Get_Char_Index (by returning either an appropriate error
and/or -1 for the glyph index) but still make FT_Load_Glyph and
friends work as expected.

David, what do you think?  Anyone here who would like to implement
this (which should be rather trivial)?
