Hey Jeff -
The expectation of drawRect is that it will repaint the entire invalid
area. I don't think there is a way to do additive drawing on each call
to draw rect. If you'd like to re-use and erase portions of the same
picture, you could draw to a bitmap context that you keep around and
draw that during draw rect.

Hi,
I'm trying to do some animation where each time drawRect is called
it's drawing over what was previously drawn, but something is
erasing the view. I've setBackgroundColor for the window to
clearColor so it's no longer drawing the default stripes but now
it's erasing to black.
Any ideas?
thanks
Jeff
