Re: disabling specific channels during view

Hi Paul - The Nuke OCIO Display node does that and also sets up a matrix transform for a swizzle with setChannelView() -- https://github.com/imageworks/OpenColorIO/blob/master/src/nuke/OCIODisplay/OCIODisplay.cpp#L337 One thing to watch out for: If I'm remembering right, this is applied before the view colorspace conversion in the display transform, so if there's crosstalk in that then you can still end up with non-zero values in channels you had zeroed out.

I've tried setting channelsHot to [1, 1, 0, 0] in the MatrixTransform::View() function but that doesn't do the right thing. I've also tried setting lumcoeff[2] = 0 but that doesn't have any effect.
