One of the things I'm not 100% happy with is that this is hard to set up,
you need to set a lot of properties, and they are sort of mutually related.

Would people want me to create a "merged" property that (if the specific
ones are missing) allows you to set "all" variables to "bt709",
"smpte170m", "smpte240m", "bt2020" (assuming ncl, and bitdepth of the trc
depends on out_format), bt601-6-525, bt601-6-625, bt470m, bt470bg? I'm
probably missing a few (see comments in pixfmt.h) but I believe these are
the most important ones.
