Just a minor annoyance, but I think that it still is a bug:

  When all the components of a blob have a pigment, there shouldn't be any
reason to issue the warning "no pigment type given" even though the blob
itself has no pigment. However, povray does issue it.
  Example:

camera { location -z*10 look_at 0 angle 35 }
light_source { <100,200,-300>, 1 }

blob
{ sphere { -x,2,4 pigment { rgb x } }
  sphere { x,2,4 pigment { rgb y } }
}
