So is what you want -- take a set of pixels intended to hit a flat  
surface, modify them so that projected onto a non-flat surface, from  
some standard reference position, it looks like the original image? (  
I'm not familiar with software to do it, but I'd bet it exists. I'm  
just clarifying at it. )
