[Mesa-dev] Second derivatives and ARB_derivative_control

Hello, I was looking at the ARB_derivative_control spec and it has this bit: It is typical to consider a 2x2 square of fragments or samples, and compute independent dFdxFine per row and independent dFdyFine per column, while computing only a single dFdxCoarse and a single dFdyCoarse
