Doh, poor performance of pixmap transfer is _the one_ blamed by ULTRIX
FAQ.

The speed enhancement of root window titling is very visible to users.
I have an idea to accelerate titling.  Build 32bit aligned block of
title in PXG memory first, then replicate it double in size, then
double it, double it...  With just a few iteration you will have a
large image, then copy and title the resulting to the target area.
