ColorNode and Render Sorting

I followed the same approach for ColorNode as I did for MatrixNode and now have the ability to define hierarchical color and alpha in Sgine. With this addition I started playing with TestCube to see how well it worked translucent. Unfortunately because I was not doing any sorting on the render list I end up with some undesirable effects:

With a simple modification to sort based on depth I now get this:

I'm doing the sort per render, which I'm sure is incredibly inefficient, but my framerate dropped from 3000fps to 2900fps in this example. I need to spend some time and make it only sort upon change, which in the test cube scenario would probably not make a lot of difference in performance since it's swapping positions every few frames, but will increase the efficiency in less frequently changing scenes.
