Rendering "radiosity.pov" from /Scenes/Radiosity in beta 10 (800x600 no AA)
gives artifacts -white pixels- along several diagonal boundaries at regular
intervals (so perhaps due to some rounding issues?) which do not appear in
3.6.1a. Reducing the blocksize to the minimum of 4 does not solve this.
There are similar 'wrong' white pixels in "radiosity2.pov" along the
base-ring which actually due mostly disappear on reducing the blocksize.

AA on the other hand smooths them out.
