I don't have compared the quality of the rendering of ghostscript,
ps2pk and ATM (MSDOS). I would appreciate if somebody does this in such
a way (TUGboat article?) that we eventually can work on serious
problems like distorted stems.

The type1 library IBM donated to the X-consortium is used by ps2pk as
pure as possible. I fixed some memory allocation problems and made
enhancements for TeX to cope with slanting, extending and reencoding. I
try to keep up with improvements (and vice-versa) made by people from
the X-consortium but there weren't any in X11R6.

I am surprised by Karl's message that ghostscript is also based upon
IBM's rasterizer. Perhaps he can tell us more about it.

All the best,
