Yes indeed, I thought the same thing only yesterday evening or so. Because 
most of the times, we only composite a small part of the image, so a lot of 
data gets wasted because we usually store data for the entire layer there.

And because we update it anyway each time a KisImage does renderToPainter it 
isn't very useful either. About the only time when we actually store the 
entire image in it is either when the image is small enough to be displayed 
at once, or when we zoom out. And when we zoom out, we don't actually need 
the entire image either since we can only display some pixels of it...
