above you wrote "I have looked into supporting TrueType in xdvi",
which as far as i understand shall mean ability to render (using
freetype library) glyphs directly from TrueType fonts, and of course
also selecting the needed glyphs of the TrueType fonts according to
the ReEncodeFont instructions from the MAP files.

yet, later you write about ttf2tfm and ttf2pk and how they are using
old freetype library etc.

i do not see any relation between "support of TrueType in xdvi" and
those two programs - ttf2tfm and ttf2pk. there is no relation
whatsoever. ttf2tfm is one of the many ways to create TFM metrics from
the TrueType fonts, and ttf2pk is, as you know, just a converter from
TrueType to PK for those programs which DO NOT support TrueType, and
thus need to fall back to use PK fonts.

could you please explain what do you mean?
