57     This extension allows texturing of the stencil component of a packed depth
58     stencil texture. Stencil values are returned as unsigned integers. It is
59     not possible to sample both depth and stencil values from the same

191     1) Should we support combined depth/stencil in one lookup?
193        RESOLVED: No because depth is float and stencil is integer and we
196        stencil in one lookup.
200        RESOLVED: Sampling the stencil values will behave like integer textures.
