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.
