*
* "Non-promoted depth (N) is active whenever the depth test can be done
* early but it cannot determine whether or not to write source depth to
* the depth buffer, therefore the depth write must be performed post pixel
* shader. This includes cases where the pixel shader can kill pixels,
* including via sampler chroma key, as well as cases where the alpha test
* function is enabled, which kills pixels based on a programmable alpha
* test. In this case, even if the depth test fails, the pixel cannot be
* killed if a stencil write is indicated. Whether or not the stencil write
* happens depends on whether or not the pixel is killed later. In these
* cases if stencil test fails and stencil writes are off, the pixels can
* also be killed early. If stencil writes are enabled, the pixels must be
* treated as Computed depth (described above)."
*
* The same thing as mentioned in the stencil case can happen in the depth
* case as well if it thinks it writes depth but, thanks to the depth test
* being GL_EQUAL, the write doesn't actually matter. A little extra work
* up-front to try and disable depth and stencil writes can make a big
* difference.
*
* Unfortunately, the way depth and stencil testing is specified, there are
* many case where, regardless of depth/stencil writes being enabled, nothing
* actually gets written due to some other bit of state being set. This
* function attempts to "sanitize" the depth stencil state and disable writes
* and sometimes even testing whenever possible.
