If the "singlewidth" glyphs are actually proportional, then this will not
generate pleasing output -- "W" is usually *much* wider than most
characters. I think it would look better to use a truly monospaced font
for the latin glyphs.

Sorry, it's an easy bug to fix (once I had a font with bitmaps to try it
out). It doesn't make Xft use the embedded bitmaps, but at least it
displays the glyphs now. I've already committed this fix to CVS so it
will be in XFree86 4.2. I'll make the new Xft library use embedded
bitmaps when not rendering with anti-aliasing.
