caveats: in order to cleanly handle the entry panel, valve, and sensor I had to rotate the valve and sensor models 90 degrees so that their in-/outlet pipes point the same direction as the entry panel. This also enables proper handling of a valve or sensor turned vertically. Some objects have rotation disabled entirely (as flipping them over/around makes no sense) When a valve is rotated, it is turned off automatically, to work around a glitch in the rotation code.
