@degasus Please review. |
Merge two cases which should've already been merged.

Piggybacking a cosmetic change on this PR, I hope no one minds. |

Works for me in OpenGL. |

Loogs good to me, but I don't recall why we clamp the zrange at all. Maybe we should look at this again after the release. |

Seems like there are some games out there which use an inverted depth range. We can easily support this in OGL, however D3D is much more difficult due to viewport restrictions not allowing an inverted depth range.
Workarounds could be used for D3D, but I don't want to merge workarounds so close to the stable.
