[bug #28590] Cairo backend displays wrong colors on X server with a different endianness

[Wolfgang Lux]

Follow-up Comment #5, bug #28590 (project gnustep):

I finally managed to track down this bug. There is an endianness mismatch for
the XImage used as backing store. In XWindowBuffer
+windowBufferForWindow:depthInfo: the image is initialized with the byte order
of the X11 display. However, the memory based cairo image surface allocated in
XGCairoXImageSurface -initWithDevice: uses the host's native byte order. I
have attached a rather hackish patch to set the correct byte order for the
backing store; probably, there is a better way to do this.
