ick, can we avoid having this? or do we need this to have this to work with the
ozone stuff? the way chromium code handles device_pixel_ratio is really bad and
i don't want to repeat it any more than necessary

We don't need it - it always passes 1.f. On CrOS it ends up getting sorted out
later by ash.
