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...
