Question about cacheDisplayInRect:toBitmapImageRep:

[oren]

Hi,
I doubt the implementation of our cacheDisplayInRect:toBitmapImageRep:
but i don't have 10.4 to test.
It seems our implementation use [GSCurrentContext() GSReadRect: rect];
to copy the existing data into the provided bitmap argument but
shouldn't it invoke -display* over that bitmap? What if the view has
never been drawn?

Apple doc says "Draws the specified area of the receiver, and its
descendants, into a provided bitmap-representation object."

Thanks.
