. Finished writing all the C++ code that should compute some indirect lighting
 => Current result is just plain crap
 => Need to:
  1) Find why it's crap (there isn't even the slightest coloring from the colored walls!)
  2) Re-write the solid set flood filler in C++ to compute the sets on the fly so I can use several probes instead of just one in the middle which will yield crap results even if there was no bug!
