I can live with that format at half fill, even though it will still be 
pillarboxed. The problem right now is that it's not even switching to half 
fill. I'll take a look at the code though.

I don't think we need a setting for this, it should be possible to pick good 
values and build in some flexibility so that it works for 95% of cases. We 
just need plenty of examples to build up these rules.
