[PATCH] Canonicalize makeOwnCopy of multipatch engine

[Richard Guenther]

Hi!

This makes the PAssert(valid) to an if as is done in all other Engines.
Fixes a problem noted by a guy that likes to mail me privately in german
rather than to the list ;)

Ok?

Richard.

	* src/Engine/MultiPatchEngine.cpp: don't assert validity
	in makeOwnCopy(), but rather ignore the request in the
	invalid case.
