DrawManager: High quality normals for non meshes

Browse Source 
This adds high quality normals for non meshes. These include

* Volumetric Object Wireframe
* Metaballs
* Extracted Curves
* Curves in edit mode

This is in preparation to fix a regression in recent AMD
drivers where the `GL_INT_2_10_10_10_REV` data type isn't
working in Polaris cards.
