Summary

0026078: bop(arg)check does not report on compounds of dissimilar types

Description

In earlier Versions booleans returned compounds of dissimilar types.
A compound of a solid and a vertex for example does not make any topological sense and a boolean with another solids fails.*)
However this is not uncovered by a bopargcheck.
And IMHO even for a single shape the bopcheck should fail for shapes like:
- A compound of (solid/compsolid and vertex)
- A compound of (solid/compsolid and face/shell)
- A compound of (shell/face and wire/edgde)
- A compound of (wire/edge and vertex)

*) A common operation (of any type of shape with a solid) would make sense IMHO. (It would return all types elements from the compound which a present in the volume of the solid). AFAIK this worked with a shell and a solid in the past.
But as shown in the example this does not currently work with a solid and (solid,vertex)

Steps To Reproduce

pload MODELING
box Box 10 10 10
box Box2 1 1 1
vertex Vertex 15 0 0
compound Box Vertex Compound
puts [bopargcheck Compound Box2 -O]
bcommon Cm Compound Box2
