That is indeed what I'm proposing. In other words, you'll always have this:
event: invalidate view
view: redraw
event: invalidate view
view: redraw
And never this:
event: invalidate view
event: invalidate view
view: redraw
This is how I believe it works based on my knowledge of the frameworks
and my experience. As to whether it matches up with reality, I would
not go so far as to make any claims there....
