this example does basically the same as my tcl snippet; it works ok with
verdana, but for some reason fails on comic sans ms and some other fonts,
but I cannot see why some fonts work and some don't. For example, also
"bitstream vera sans mono" fails wheras "andale mono" works. Maybe I
should mention that all these fonts are displayed correctly in the
canvas. For the "working" fonts I do not even need to pass a fontmap to
postscript().

I have already seen these, however they don't help me much, because of
the strange problems described above. So I am still not sure if it's
improper use of the fontmap or some other weird problem with either Tk or
maybe my system's postscript engine.
