Noticed something else today after actually opening the resulting image.

PNG file is different from the render display window or BMP file output, 
both of which look correct. For the png the nearest object to the camera (a 
mine) has a pink color on the shadowed, or opposite, side of the main light 
source. There are several lights, two of them using negative color values 
(in light_groups with two mines) and two light_source's as shadowless, with 
the main light being rgb 5. I should say I have changed some of those light 
colors and media values but the scene is basically the same as the original.

I can't explain the reasoning for the png and bmp/display window differences 
myself, since I'd expect to see other parts in the scene to do the same not 
just one object. Unless, of course, it might have something to do with a 
light_group or various interactions. I just thought it peculiar how the png 
turned out differently and maybe someone might understand why.

If anything, like this changed scene file and rendered image, are needed to 
be seen I'll happily post them to the beta binaries.
