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