I'm a bit confused... We're currently contemplating complete
removal of the XFree86 libfont bitmap font scaling code. Why
would one want scaled bitmap font code somewhere else?
I ask only out of confusion. Scaled bitmap fonts are ugly, and
IMHO any code permitting scaling of them should default to off,
and be configureable. Or am I off base here?
