/* Intel hardware is fairly sensitive to whether or not depth/stencil writes

 * non-promoted case which means a fairly big performance hit.  From the Iron
 * Lake PRM, Vol 2, pt. 1, section 8.4.3.2, "Early Depth Test Cases":
 *
 *    "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.
