Well, I wouldn't say that exactly.  I generally don't like making modifications
to the TCL itself, but this is the one place where I have made an exception.  I
simply changed the IWindow() method to create a color window using NewCWindow()
if the Mac has Color QD.  I have done several things using this code, and I
have had no problems.
