Can you explain a bit more what this format looks like? I have never 
heard of an application for an RGB24 image with "lines swapped". But I 
also know that 3D graphics hardware can require strange things of source 
images.

Do you mean that lines 0 and 1 are swapped, 2 and 3, 4, and 5, etc.? If 
so, I was wondering what theoretical foundation drives this design?
