Note that we currently only have the one (sampler::min_lod), and the other is a synonym for the same value that has been introduced by this branch. Those GL values are currently both consolidated down by the mesa state-tracker (along with other stuff) into sampler::min_lod. Although Michal has chosen a different name for the new member, it has the same meaning and the GL semantics can be implemented on top of it as they currently are for sampler::min_lod.
