Colour Corruption on remote X11 with different endians

[David Chisnall]

Hi Everyone,

I've done a bit more testing with GNUstep and remote X11 with the X  
server running on PowerPC (little endian) and the apps running on x86  
(big endian):

With the xlib back end, everything is fine.
With the art back end, almost everything is fine, but pixmaps have  
their colours inverted.
With the cairo back end, everything has its colour inverted.

Since the xlib back end lacks a number of features, this isn't  
ideal.  It is also, however, a lot more responsive than the other two  
(with art being slower than cairo).
