I've got an NSView subclass with a rather expensive drawRect: operation,
but there's a quicker, less accurate substitute that's good enough for
resizing the view. I'd like to have window/view resizing invoke the
quick version, but then go back after the mouse is up and perform the
final, slower draw. How can drawRect: distinguish between the zillions
of intermediate draws and the final draw?
Btw, I've noticed that NSSplitView actions generates an update after the
mouse up, but NSWindow resizing doesn't, so I can't check the mouse
down state. I'm guessing I have to generate some sort of event or
notification?
