"OpenGL, per spec as published, does not have the feature set that the current display renderer does. It strikes me as cutting off the nose to spite the face." 'cept modern cards support Opengl and accelerate it.. the current does not.. so, how does it have a better spec? it does not support transperency properly, lighting effects, modern speeds or lightening the load on the CPU for what is really a secondary task, eg, the preview, when teh CPU coulf be gainfully employed with other tasks. please explain why you think a backwards step is a good one?
