I think this would be cool, but unnecessary. I just thought about it but the 
X11.app must be on top of Carbon/Cocoa because we can use the Desktop without 
X11.app. This means that X11.app either uses Carbon/Cocoa interface functions or 
works beside it. I think Carbon here is definitively the faster way to go...

Why I was asking this question is more meant by: will or must there be added 
more Core Mac Graphics functionality in the future and if this is true then 
might it be better to use the same code than the traditional *nix systems?

Good question, and my last question to John here before I prepare a changeset 
tomorrow: Do we need a configure test to check for the LDFLAGS '-framework 
Carbon' or can I just add this to the '*-*-darwin*)' flags of the 
canonical_host_system in configure.in?
