As a first embryonic try for this idea, it might be enough to try to
intersect the previous object that was hit. If success, then time is saved;
if fail, go back to normal process, and no significant time was lost. I
think that statistically (I insist heavily on that word), we can gain
something because most of objects occupy an entire area of the scene, more
or less, even if they are plenty of them.
