I've noticed (in a rather painful manner) that the pixmap handling
code in Xqdss is amazingly slow.  For example, creating a 1000x1000x8
pixmap and then filling it with WhitePixel using XFillRectangle takes
over 2 minutes!  (This is quite worthless, considering I was hoping to
do double-buffering).  Does anyone know why this is so, and if so how
to fix it?  All rendering routines appear to be this slow.  (like 15
seconds to draw a small 4-sided polygon).
