Support cropping of content on playback (#3041).

This is to allow, for example, pillarboxed 1.78:1 DCPs to be played nicely
on 1.78:1 projectors.  DCP-o-matic can now crop the pillarboxing before
display, rather than putting the pillarboxed 1.85:1 onto a 1.78:1 monitor,
thereby adding letterboxing.
