: incorporated fractal patch - completely untested
fractal_interior_type and fractal_exterior_type do not work (they are
recognized as keywords but they are not parsed). The reason is that
you haven't added the following code at line 1067 of parstxtr.c:
CASE (FRACTAL_EXTERIOR_TYPE_TOKEN)
New->Vals.Fractal.exterior_type = (int)Parse_Float();
Parse_Comma();
New->Vals.Fractal.efactor = Parse_Float();
END_CASE
CASE (FRACTAL_INTERIOR_TYPE_TOKEN)
New->Vals.Fractal.interior_type = (int)Parse_Float();
Parse_Comma();
New->Vals.Fractal.ifactor = Parse_Float();
END_CASE
Adding those lines fixes the problem and all my test images (those I have
posted to p.b.i) work fine.
Thanks for removing the //-comments from the source file. However, there
still are few of them in lighting.c, povray.c and tokenize.c.

: radiosity uses perturbed surface normal (bumps, wrinkles, etc)
Why is it so slow with them? My test scene (included below) takes
1 minute and 10 seconds to render without the normal map. Adding the normal
map takes more than 10 minutes to render.
If this can't helped, then I think that it should be an option in the
radiosity-block (turned off by default).
And another thing: It doesn't seem to work very well. Just try it:
