Is it valuable to run the HDR tests on this hardware? As far as I can
tell the tests are failing because the plane scaling is invalid, but
from my interpretation of the test matrix it's fine on newer hardware
which support HDR.

I'm not sure whether to add something to just skip the tests for
older[0] hardware entirely, or to fiddle with the test so this hardware
is happy again.
