Correct clamped depth range from [0, 65535].
...
This changes a few things:
* All backends clamp the depth range and keep it positive.
* The depth rounding uniform is now properly dirtied.
* Projection is updated to translate and scale appropriately.
* Depth rounding is halved on OpenGL to account for [-1, 1] range.
Fixes Phantasy Star Portable 2 without the need for a game-specific hack.
