Picking Issues

Picking of OpenVolumeMesh objects is strange.

When the picking rendering plugin is used, and an edge is selected, the rendered edges are bogus.

Steps to reproduce:

• use picking renderer
• Add a volume mesh (e.g. tetrahedal cuboid)
• enter edge selection mode for volume meshes
• pick an edge of the added mesh.
• watch the magic edges being randered arbitrarily.

Strangely changing back to the default internal renderer fixes the mess up, but the rendered mesh looks different in the picking renderer.
