Summary: Clipper should preview the result of the clip operation
In 1.5, the brush module does not support rendering the region-to-be-clipped.
This was removed for performance reasons, and should be reinstated in an
The previous implementation would copy the selected brushes and re-compute
their intersection with the clipper plane every time a gl view was updated. It
would be simple to optimise this by using a callback to trigger updates only
when the clipper plane changes. Another optimisation would be to draw only the
polygons resulting from intersection of each brush with the clipper plane - one
polygon per brush.
