/* helper function to correctly open Xft/core fonts by name
#### Can't we use FcParseName here?
#### Is this done so often that the logic needs to be hard-coded in C?
Daniel Pittman sez: Older code tried to enforce that an XLFD font was
not scaled, while this version just doesn't care. I think that is a
better behavior, since if someone really wants a scaled font we should
oblige them.
Stephen sez: This whole function was ill-conceived, and I'm not sure it
succeeds at any of the things it attempts to do. First, we should be
using fontconfig directly. I'm not sure what Xft (or fontconfig) will
try to do if passed an XLFD. As for scaled fonts, both options are
equally bad. The problem is that the X server will often scale bitmap
fonts willy-nilly; it's worth trying to avoid that, but I can't say
whether that's worth overriding somebody who knows what they're doing.
In any case, I think we should find out what Xft (fontconfig?) is able
and willing to do with XLFDs, and probably move the logic to LISP.
