The fallback is there because 1 bit stencil is the minimum required by the opengl specification, so it is possible that somewhere there is a driver that only supports 1 bit stencil.
I understood that, I was simply saying that I don't think there's ever been a consumer graphics card that did only 1-7 bits -- they seem to universally do 0 or 8 bits of stencil (even the software-renderers), so the fallback is likely a waste of breath, though I appreciate caution. Perhaps more to the point, does D3D only guarantee a 1-bit stencil buffer? A 1-bit stencil buffer (most especially one without GL_EXT_stencil_wrap) is of very, very limited use. I somewhat expect that no D3D applications (except maybe, just maybe, some very simple test-apps) will actually operate correctly with a 1-bit unwrapped stencil. Cheers, --adam
