Is it possible to clear only a certain rectangular area of a window
instead of having to use GrClearWindow()? I have used GrFillRect() when
the background is solid, but what about when the background is a pixmap,
using GrSetBackgroundPixmap()?
You could GrCopyArea() from the original pixmap to the window, but what
is the background is tiled, stretched, etc?
Be whole lot quicker if it's a small area compared to the entire window.
Especially on a several 100Mhz embedded processor.
