My idea was to force blur to trace at least in example 5 first rays per
pixel, even if they are identical to eachother and even if otherwise they
will be bellow threshold,

one liner:

     }
   }


of course it is better to just set Sample_Threshold for min_sample first
value to 0

So the idea is to bump up minimal rays traced without affecting rest of
adaptive system... 

I will do some testes after weekend probably
