cutealien 3752bd9bd4 Add more transparent node sorting algorithms 
Adding 2 algorithms to sort by distance to camera plane instead of camera position.
This is better in quite a few situations and extra cost is just one vector subtraction per node and an additional function parameter per call, I think that's worth it. So made the camera-plane to object-center now the new default.
