This reverts commit 0543630d0b.
It caused flickering artifacts in Steam games such as Team Fortress 2 or
Left 4 Dead 2.
We could probably only enable this optimization by also making sure the
shader code only uses either SI_PARAM_LINEAR_CENTROID or
SI_PARAM_LINEAR_CENTER, not both. This would probably require a shader
variant.
Sorry I didn't remember this when reviewing the reverted change.
