This was purposely written as a separate constant. Can you give an example of
when this is doing the wrong thing?

   for (size_t i = 0; i < tilings_->num_tilings(); ++i) {
     float tiling_contents_scale = tilings_->tiling_at(i)->contents_scale();
     float ratio = PositiveRatio(tiling_contents_scale, scale);
