Jules Blok a141e91dd2 OGL: Check for GL_DEPTH_CLAMP support.
It's not available in OpenGL ES and officially it's not supported on OpenGL 3.0/3.1.

Fallback to old depth range code if there is no method to disable depth clipping.
It's more important to have correct clipping than to have accurate depth values.
Inaccurate depth values can be fixed by slow depth.
