I realize that the math doesn't exactly work out right, so I expect
this is more of a compiler issue. However, I was clearly ending up
with a negative number for part of the calculation. The monitor
resolution is, in fact, at something like 2560. When I get the chance
(I'm on vacation right now), I'll send you an annotated list of the
equation results through that section of code. My solution may just
be a "workaround for stupid compilers", but at worst, it's a harmless
algebraic manipulation.

I sent a patch to Richard Levitte; I can forward it to you, too, if
you like. I'm using my modified version all the time, now; it looks
great! My only problem with it is that all the Xft fonts appear to
define rather overly generous ascent and height values that are way
out of proportion to the same measurements on equivalent X11 fonts.
I've noticed this problem on Tcl/Tk and xterm and other software that
has switched to or added Xft font support. So I added an empirically-
derived adjustment that needs a bit of tweaking to make exactly right.
Regards,
Tim
