Create a clipping path. Within the block create an outline from one or more
paths, basic shapes, text objects, or use. Everything drawn
within the outline will be displayed. Anything drawn outside the outline
will not.
If the clipping path contains a use, it must directly
reference path, basic shape, or text objects.
Attach the clipping path to an object with the :clip_path style.
