Specific Errors:
    PK_ERROR_cant_merge_regions   solid and void regions would be merged
    PK_ERROR_not_general          faces do not belong to a general body


The faces must all be from the same general body.  The faces are
deleted from this body along with any edges or vertices which cease to
have adjacent faces.  It is an error if any of the faces separate
regions of different types.
