I am glad to see that things are going on. But what about direct CID-access
to a font program?

I am busy with reading PDF-Files. So called Type0-Fonts require a
CMap-parser (as well as ToUnicode-CMaps are to be read).

I *MUST* parse the CMap myself because the Subfont may be accessed by
a CID (embedded CFF) or a GID that is converted from the CID by a
special array (embedded TrueType).

Even if I use FreeTypes CMap-Parser I need CID for a number of
reasons (determine the glyphs width e.t.c).

So, after loading a CID-keyed-CFF-Font I am missing:
- FT_Load_Char() works with CID instead of charcode OR
- FT_Load_Glyph() works with CID instead of charindex OR
- "FT_Load_CID()" is created.

As fas as I know - there is no chance of loading a glyph by CID until
now!
