NSView and layers?

Hi,

Is there a somewhat simple way to be able to draw into (visually, at least) an NSView without causing the existing contents of the view to need to be redrawn?

I checked out the GLChildWindowDemo sample code, and it can do this. However, my view is contained in a scroll view and I need to be able to alter the contents of the "layer" based on the scroll position. This can be tricky, at least with what I'm doing.

Any advice? Thanks.
