[Bf-viewport] Proper handling of normals

[Ton Roosendaal]

Hi,

Let's not turn this list into a feature request discussion.
Design for tools (mesh layers, modifiers) is only slightly related to what we want to achieve. A better normal editing feature would automatically work in new (or old) viewports.

I also prefer to have people talk here who are interested to help out as developer and designer.
