Drawing tools limitation with composite images

When drawing on a composite image (like Organ of Corti) it is not possible to modify any channel other than 0. This is similar to IJ1. One needs to split channels or edit colors so it is grayscale and draw on specific channels. Think what the best behavior is here.

(Ideally we'd have a drawing "color" that is a collection of channel values. That "color" would get modified by the picker tool based upon the hit testing within the image selected [gray, color rgb, composite]. Not sure this is really workable.)

Note that in IJ2 the channel that gets drawn on corresponds to the current channel slider position. So you can draw outside channel 0.

This ticket no longer is valid. We implemented the approach as described in the second paragraph of this ticket's description. Recent changes to drawing tools make them draw all channels at once.
