No, all I changed was the order of RGB within a TrueColor visual as well 
as switching from depth 15 to depth 16 (a better depth fix would be nice).

Remember that this change was only designed to make legacy toolkits 
operate with ARGB visuals.  I have hacked xterm to kinda work in this mode 
with these DIX changes, but it still took a lot of fixes within the xterm 
code to make it all work more-or-less correctly.

Applications using the "normal" visuals see no change in any case.

If we think a change like this would be useful, we can go back and figure 
out a way to do this without modifying the visual structure.  It's not 
that hard -- it's almost always just the bits in depth with those consumed 
by RGB taken out.
