One subtlety which did just come up on IRC and should probably be
documented, is the interaction with the 'Broadcast Mode' property.
Currently, Broadcast Mode logically sits on top of colour management:
all tables passed into CM are assumed to be for 0-255 colour ranges,
and setting limited BM instead clamps these tables at apply time to
16-235 (by manually adjusting them in the driver).

It'd be nice to document this, so someone doesn't implement this the
other way around, or assuming that CM trumps BM, or ...
