Is there a "standard" method for determining if a font is fixed (all 
characters the same width) or proportionally (each character has a
unique width) spaced?

I've tried checking to see if the min_bounds.width equaled the 
max_bounds.width (in the XFontStruct).  This works great under Motif, 
but under OpenWindows the min_bounds.width is zero in most cases (even
fixed).  This may be because many OpenWindows fonts cover all 255
chars where the X fonts covered 32 to 255 only.  The first 32 under 
OpenWindows would be of width 0 (undefined)???

Another method is checking to see if the XTextWidth() of "M" is the
same as "i".  But this is fairly kludgy.

Is there a better method that I can use?
