Halo is rendered after OnPostRender, resulting in Halos not being affected by image effects.

Steps to reproduce:
1) Open the attached project.
2) Enter play mode.

There is a cube in the middle of the scene. A halo is rendered on top of it. On versions, prior to Unity 5.4, the Halo is not visible.

Expected: Halo is not visible (rendered before OnPostRender)
Actual: Halo is rendered on top of the cube (rendered after OnPostRender).
