Whoo hooo!

I worked. It actually looks pretty nice for the main GUI. What you  
need to do is to copy grass7.app/Contents/MacOSX/bin/wish8.5 to wish.  
Hopefully, this can be worked out in the compilation mac.app step.

The TclTk interface has some visual issues, but nothing that would be  
too hard to clean up if I knew that we were going to go with TclTk 8.5  
aqua. The special color picker does work right, but I could just  
switch that to a native TclTk color picker rather than the custom one  
that is used. It crashed on trying to open vector point thematic  
mapping. I don't know if that was because it has a problem there or  
because it had just accumulated enough small errors. I also got the  
bogus -label error on hiding and showing the control panel. It's  
probably not hard to fix, just to track down.

This means that GRASS can run entirely without X11 on the Mac, but  
still have access to a terminal. And an x-window can always be opened  
if someone wants to use the old display drivers.

This also means that there is no reason not to compile open GL for  
aqua in GRASS 7. Maybe we can now get the NEW nviz in wxPython to  
compile on the Mac too. I'd like to take a look at it.

Thanks for
