  What I did was to deepen the normals ten-fold, reverse them (for some
reason they are reversed and need a negative bump_size), changed the
normal accuracy (I don't know if it has a real effect or not), added a
background color (which the original scene didn't seem to have for some
reason), copied the radiosity settings from rad_def.inc and increased
the 'count' and added 'normal on' and changed the assumed_gamma to get
a higher contrast.

  (Besides that, I reduced the disk space needed by the scene from 18 MB
to 9 MB. I did this simply by converting all the tgas to pngs and by
removing 2 megabytes of no-op content from sponzaM_o.inc.)
