    Summary: Bug in clipped text output using PurduePlus speedups

This bug occurs when text (of fixed width <= 8, thus the Purdue+ text speedup
is being used) is output to a window that has either a gcontext clip mask or 
a server clip mask (because of occluding windows).  The manifestation is that
when a string is drawn that spans a vertical clipping line, a vertical strip of
a couple pixels is left out of the characters that span the boundary between
the clipped and non-clipped regions.

I guess it's an indication of how few people are using the Purdue+ speedups
that we were one of the first to notice...
