basicly - using 
error 1 nearest 7 and count 30 gives smooth shadows but ignores detalis

error .5 nearest 8 and count 200 gives details but sometimes artefacts are 
visible

error .4 nearest 9 and count 1000 gives both details and smooth gradients 

(Basing on my lava scene in .b.i - but probaly typical scenes with normal 
light sources will look nice with count like 20,100,200, and recursion 4, 
instead of 8)
