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

[Jean-Paul Vignault]

Here is better : just add "newplan" after your plane in fusion object.

In fact, in solides.pro you have 2 types of object : type solid (edges
+ faces + colors and so on) and type "plan" (range + origine + grid +
...). When you want to draw a plan type object, you need to transform
it on solid type. This is automatic with \psSolid[object=plan], but I
forgot the fusion case.

The command "newplan" make the conversion plantype --> solidtype
