Probably the best way to do it is found in most of the older paint
programs like Neopaint. What they do is scale up a segment bordered by the
mouse pointer by multiplying a factor. For example, if you want to zoom in
on a segment in your picture by a factor of 4, a red pixel in that segment
would end up filling 4 pixel positions in your zoomed up view. The problem
with this approach is that the area being magnified would appear coarse
around the edges.
