Bug Description

Currently, the layer display just says "Shape" and the label is some generic shape message.

Expected Behaviour

1. The layer icon should be "shape" icon.
2. The layer display should show the actual shape (possibly with fill and shadow for blending fills as we do for images now).
3. The label should reflect the shape/mask name. E.g. "Heart" and not just "Shape".
