This is a very good question. I am writing on Mac OS X with Cocoa and
need to create an offscreen GWorld as a destination for a VDIG. Do I
still need to care about memory being moved around by the Memory
Manager?
I was not able to find any documentation on this topic (something
like Carbon for Cocoa programmers would be nice).
I am crossposting this reply to quicktime-api as well.
