86       near clip plane, it should be rendered with the zw value min(n,f)
89       plane should be rendered with the zw value max(n,f).
95       position zw to the range [min(n,f),max(n,f)] where n and f are
98       This rule ensures that the raster position zw will never be outside
101       otherwise a raster position zw could be specified outside the [0,1]
103       is subsequently disabled, that out-of-range raster position zw
109       pre-clamped zw is 2.5.  Because depth clamping is enabled the
110       raster position zw is clamped to the current near and far depth
117       the bitmap fragments are generated with a zw of 0.9.
121       zw depth component clamped to 0.8.  But if the depth range was
123       bitmap fragments will have a 0.9 zw depth component since then
136       fragment's zw, but depth clamping if enabled will subsequently
137       clamp this new zw.
194     zw is first clamped as follows.  If the raster postition's wc>0,
195     then zw is clamped the range [min(n,f),max(n,f)] where n and f are
210     fragment's zw is compared, zw must first be clamped as follows: If the
211     fragment's wc>0, then zw is clamped to the range [min(n,f),max(n,f)]
