OK, thanks for the clarification.
A bit odd though - on Tiger I was using a transparent colour with
NSRectFill and that worked OK, whatever was drawing "underneath" came
out as expected. On Leopard, it still draws that rect OK, but anything
drawn underneath this rect (using the usual bezier path fill/stroke
methods) suddenly draws in a different composition mode, as if the
underlying graphics context got changed to something else but not
changed back by the NSRectFill.
However take this "analysis" with a pinch of salt because I didn't
pursue the problem, I just changed to not using NSRectFill.

To draw on top of existing color rather than replacing it, you don't
want NSRectFill. There you want NSRectFillUsingOperation with the
NSCompositeSourceOver operation. That should be considered the
'normal' drawing mode, so it's somewhat unfortunate that the nice
convenient looking NSRectFill uses copy mode.
