for non-integer translations we still need GL_LINEAR, don't we?

Excellent point. I've changed this to use isIntegerTranslation() instead.

             quadSink.append(TileDrawQuad::create(sharedQuadState, tileRect, tileOpaqueRect, tile->resourceId(), textureOffset, textureSize, textureFilter, tile->contentsSwizzled(), leftEdgeAA, topEdgeAA, rightEdgeAA, bottomEdgeAA).PassAs<DrawQuad>(), appendQuadsData);
         }
     }
