[pstricks] can planes be fused with \pSolid surfaces? a desperate plea

[Zbigniew Nitecki]

Thanks, I'll try this out eventually (although looking at the code,
I am not clear on the syntactic role of "newplan" in the definition of TEST).

Juergen suggested using object type grid instead of plan, and this has worked fine
(except that I have not succeeded in getting any transparency in the fused object).
