More food for thought:

Using an fbo which is bigger than 1x1 is a waste of space since we only want to
know Z values. Using a 32x32 fbo with some custom shaders we could handle 32*32
entries and so on.

With some more shader magic maybe we could have the left half of the fbo for
minZ values and the other half for maxZ values?

Am I dreaming or is this doable?
