As I know nothing about the Xserver internals, I'm going to avoid any
'optimisations' like this as being premature. Wiser folk than I can
tweak what I create - if it works.

It's probably going to be orthogonal, but I am not going to spend time
trying to make it so. If it works - great, if it doesn't - well as soon
as I have something prettier than a dozen blank windows on the task bar
(The current state :}) you'll get a patch and can play to your hearts
content. All the needed doco to build the test tree is now on record..
