Yes, yes, because POV-Ray blobs are not the original blobs (Blinn 1982) but
a variation of blobs (Wyvill 1986) and this confuses me every time I think
about blobs.  Essentially all what needs to be done is to implement the Binn
blobs and allow switching between the methods.  Oh, and btw, somebody should
really add complete quadric support...
