Somehow I thought (perhaps because that's what I discussed with
Stefan) that he added an explicit FBO check to
CheckDepthStencilCapability to separate FBO and classic WGL. In the
FBO path he can use the detection he uses now augmented with a
'supported' check. At least that's what I had in mind. I prefer to
limit the use of IsPixelF* to wgl stuff like checking whether an
adapter format is supported and for the non-FBO case. Float checks
would help in the non-FBO case to prevent getColorBits warnings.
