Ok, great. I'll try fixing this in a PR.

I am hoping to use dlib for image manipulation utility program

I've done this by declaring a static array of the same length as
ViewColor!V.channels, and foreach-ing over the channels in a
colour, but this seem uglier than it need to - it would be nice
if I could just define + and = appropriately on double[] and
colours to do the right thing.
