* nothing is rendered into the color buffer, but for each pixel that would
* be rendered, a non-zero value is placed into that location in the depth
* buffer. With depth test enabled, pixels will only be rendered into the
* color buffer if the corresponding value at that (x,y) location in the
* depth buffer differs from the incoming depth value.
