Hopefully, the two paths can share some code. I've been thinking, it looks reasonable to statically check whether the lod/grad/bias is shared at the glsl level. Then we could have separate opcodes for the texturing variants for when we're sure things are shared and when we aren't. And pay the cost only when it is needed. Would that sound reasonable?
