[Mesa-dev] [PATCH v2 03/10] radeonsi: restrict cube map derivative computations to the correct plane

From: Nicolai Hähnle As remarked by the comment in the original code, the old algorithm fails when (tc + deriv) points at a different cube face. Instead, simply project the derivative directly to the plane of the selected cube face. The new code is based on exactly
