I wish povray dropped the old radiosity engine in favor of the photon mapping
industry standard for GI, not just caustics.  Photon mapping seems to solve
many problems that radiosity can't, including more sharp shadow projections,
subsurface scattering etc.

like in "tweaking a scene by hand to get faster renderings"?
