Actually Shape is CSmartPtr<IShape>, this is why we cast it to a IShape*
before (CSmartPtr define a cast operator). Hence the cast should be ok and
valid.

Maybe the problem is with the cast operator (or a conjunction of the 2). NB:
the patch of loic dachary in scene.cpp, line 473, is maybe based on the same
problem.
