That will work, but that strip which doesn't get redrawn is also where Acme
won't see the mouse as being in any window or tag. Since it's sometimes useful
to see it, you might want to draw it in display->back or display->white, I
guess. If one of those is already your background color i guess you'll need a
new global pointer for a new color, or maybe use an existing color which
happens to be subtly different.
I'm not posting my code, my brain switches off half-way through finding out how
to do it, and then I forget what I've done until I want to post it here and
look it up...
