Take a look at http://www.freetype.org - there is no dependency on X11 at all
(check that again, but I'm pretty sure about it) the library just renders
type1, truetype and others to bitmaps. By now, it is the standard font
rendering library under Linux so support is pretty good. It is plain ANSI C,
no dependencies at all, portable to about anywhere. XRender builds upon
freetype. TeXmacs should probably use the original library to be really
portable.

Antialiasing is not part of that library. But as I see it, there is no need
for it in TeXmacs anyway? Everything is just rendered BW to 600dpi (or
whatever printer resolution you use) and scaled to screen resolution
grayscale. So what do you need antialiasing in the font renderer?

Under Linux .ttf is becoming more and more common. Quite a number of quality
scalable fonts are distributed freely. (e.g. the Vera font family, recently
donated by Bitstream to te open source community)

As I said above: freetype definitely is the standard way
