From: Roland Scheidegger <[email protected]>
This optimized filter (when using repeat wrap modes,
linear min/mag/mip filters, pot textures) only applies to 2d textures,
but nothing prevented it from being used for other textures (likely
leading to very bogus sample results).
Note: This is a candidate for the 9.0 branch.
