Review request for Calligra.


Summary
-------

This patch implements clipping for shapes using arbitrary clipping paths. This is needed to properly support svg clipping.
There is a new class KoClipPath which can be set on a shape. The clipping path is then used when painting the shape to set the clipping path on the painter.
There are also two commands to set and to unset a clipping path on a shape.
