The bug:
- Primitives rendered with Gizmos API appear to be displayed without lighting if using a Gizmo matrix with negative scale on odd number of axes.
- When selecting an object with a MeshRenderer that has negative scale on an odd number of axes, Gizmos using a matrix with negative scale on an odd number of axes appear with lighting, but Gizmos using a matrix with negative scale on an even number of axes appear without lighting.

To reproduce:
1. Open the test scene in the attached project
2. Select the different "Mesh Cube" objects in the Hierarchy view and observe how lighting on the cyan "Gizmo Cube" objects changes.

Reproduced on 4.2.b3 and 2017.1b3
