  The fact that a scene is legal in a syntactical and logical sense does
not mean that you can't hit the pysical boundaries of the processor (eg.
floating point accuracy).

  Also this scene is perfectly legal by all means, but it renders horribly
due to limited floating point accuracy:

camera { location -z*2e5 look_at 0 angle .001 }
light_source { <100,200,-300>, 1 }
sphere { 0,1 pigment { rgb 1 } }
