Description (last modified by bdezonia)
Right now DatasetView has a method that can take a set of data values and turn them into a ColorRGB. This is needed in a couples places in IJ2. Unfortunately it is done by replicating a compositing algorithm from the Projectors code of Imglib2. We need to change the Imglib projectors to allow one to query them with values and get values back as a result. So you could query a projector with channel values and get the RGBA type value back. Then eliminate the code in DefaultDatasetView that copies the Imglib logic.
(One thing to wonder; how will these two areas of code be affected when ticket #721 is addressed)

Hinerm, you've done work on the projectors. Would you be willing to tackle this? The method in questions is DefaultDatasetVIew::getColor(channelCollection).
