I found another strange thing in the radiosity code: There is a 'scale'
factor in the ra_gather() function (file radiosit.cpp) that is used in
line 794:

VAddScaledEq(Colour_Sums, scale, Temp_Colour);

to scale the color.  It's value is set to 1.0 in line 668 but not used or
changed anywhere else.  It seems to be a remainder from megapov when there
was a 'PHOTONS_DIRECT' switch - i'm not sure what it was about.
