[Tom Goddard]

Fixed.

Added drawing argument to constructor call. I guess we never have used Drawings with atttribute clip_cap = True. I don't know a simple test case for this. I tried setting clip_cap on all drawings and it showed a new clip cap but did not move it for atom spheres. That might be another bug related to updating clip caps on Drawings or instanced Drawings.
