Yeh. It's a nicer interface, but as for vout on non MCO systems there
doesn't seem to be a way to save anything - which is a pain on both sides!
(hint hint to anybody that can fix this) - we've run into problems with
trying to set and save the PAL/NTSC output area....

That's why I recommended mcogamma, you can read in the gamma ramp from a
file. So you can also exec it from inside an application (there doesn't seem
to be an API version of it as there is for gamma [gammaramp])
