pie menus, hrm.

Hrm. I've got my t-cube implementation working. You can actually use
it instead of xscribble. Feel free to suck down a copy and try it
yourself: rcp guest@skiffcluster5.handhelds.org:russnelson.com/t-cube1/t-cube .

Unfortunately, the standard manner in which pie menus work is to warp
the pointer if you're too close to the edge of the screen to be able
to stroke in that direction. But that only works for relative
pointers. Fails miserably for absolute pointers. I could remove the
warp, but if you're too close to stroke, you're too close to stroke.

Back to the drawing board....
