When the KoShapeContainer was introduced it had a 'clipped'
property which implied two things;
 * the shape is clipped to the outline of its parent container.
 * the shape inherits the transformation of its parent container.

When I used a container, now 4 years later, I was confused why my
shape didn't inherit the transformation and only by reading the code
did I figure out thats because I designed it that way...
Now it doesn't make sense to me anymore that one implies the other,
the connection between them is a bit thin.
So, split up the two properties and provide plenty of API docs on the
matter.

Incidentally, this helps a usecase where I need the inherit concept
but not the clipping concept ;)
