That is good to know.

I see. For compatibility with future clients that require Composite, 
we eventually will want to provide Composite with XDarwin DDX using 
Mac OS X's built in backing buffers.

Yes, I've had discussions with them about what the best way to go is 
for their next release. There is a related technical issue that their 
last release did not actually use the XDarwin DDX, but instead used a 
customized version of it (hw/apple). Apple does not want to continue 
to maintain their own DDX in the long run. I've been working hard on 
making hw/darwin a feature complete replacement for hw/apple. We 
still need to determine to what extent they can switch over to using 
hw/darwin for Tiger. The closer Apple's X11 is to standard XDarwin, 
the later they can afford to wait for an open source project's 
release before beginning to package for Tiger.
