**Issue description:**
height display matches dx normal space, instead of ogl normal space.

in all scenes hdr light is turned off, light value is 2.

**Steps to reproduce:**
- draw something with height
- compare the shape to matching geometry shape in 'lit' mode
- compare color pattern in 'normal' mode with baked ogl normal map and dx normal map

Reproduce the issue by drawing height, comparing the shape with matching geometry in lit mode, and comparing normal mode against the attached Blender-baked OGL and DX normal maps. Done means the drawn height matches the OGL normal-space result rather than the DX result.
