This feature greatly increase depth buffer precision. This is very noticeable in large view distance scenes. This is enabled by default on GPUs that supports it (most of the hardware we support already supports this). This makes rendering different on the GPUs that do not support that feature (`glClipControl`). While this give much better depth precision as before, we also have a lot of imprecision caused by our vertex transformations. This can be improved in another task.
