CopyBits works just fine on different screen depths, even
from a screen (window, grafPort, CGrafPort, whatever) of one
depth to one of a different depth.

As to your second question, I think that CopyBits would work
just fine outside your windows, although I am not real keen on
writing to the desktop port, as that doesn't sound very Multi-finder
compatible....
