Is there any way to draw an NSBitmapImageRep while respecting the alpha channel, i.e. to make the transparent parts actually transparent instead of black?

I don't think there's any public API for this, and it used to simply not be possible. However, I am pretty sure that Quartz can composite straight from a user-supplied bitmap, and the stack-traces Nat! presented contained some interesting methods...
