Are we sure doing GUI calls in event handling is a good idea? Since win
3.1 the recommended way was to schedule an update and handle it in the
'preferred' event...

Also how do you do an 'incremental' opengl update? An FBO for the
current screen and then a paste over with the current modifications?

Threads are not free, either... I personally would be doing this with
coroutines but only scheduling the updates, this also help detach the
drawing code from the tool process/state machine (like in MVC, ideally,
the coroutine is the controller part and the paint code is the view).
Yes, I know that doing a 'pure' MVC is neither easy nor fun but in the
long time I think it would be better than interspersing drawing with the
controller.
