--
-- The approximations used when

-- are implementation defined. Some implementations /may/ interpolate
-- between fragment density levels in a subsampled image. In that case,
-- this bit /may/ be used to decide whether the interpolation factors are
-- calculated per fragment or at a coarser granularity.
