gs_cff.ps does not load TTFs.  It has a very short procedure
(.loadottofontfile) that reads the TTF table directory, searches for the
"CFF " table, and then skips to that table and reads it.  I think sharing
code from the TTF loader in gs_ttf.ps would only shorten gs_cff.ps by about
10 lines, so I don't think it is worth it.
