That's what I don't understand. If I don't specify assumed_gamma I expect some
default value of it. And documentation says (6.11) it has default value equal to
display_gamma which is default equal 2.2 on windows platform. So I expect no
assumed gamma is equvalent for assumed_gamma 2.2 (eventually 1.0 as linear
copying of sky).
