Please note that OpenType and TrueType are really two different formats. A
quick check shows that mkvmerge actually distinguishes the types. On the
other hand, any font handling library would probe the format anyway.

I do not know which one would be better: state that CODEC_ID_TTF really
means CODEC_ID_FONT for any font file format, or create a new
CODEC_ID_OPENTYPE. Both have pros and cons. On the long run, the second is
probably slightly better.
