LEDDomeVolumeVisualizer has symmetry issue

[Ashoat]

While running this visualizer in the simulator, I noticed that something is wrong with the way it handles the dome geometry. It's supposed to rotate the animation along the dome along with the beat, but there is some asymmetry in one of the rotation states. I think this is probably because of some bug in the StrutLayoutFactory code, but it could possibly be deeper (either in the simulator code or the actual output code). We should get to the bottom of it and fix it
