Also fixed a bug where a pipe "entry panel" would
report full of water if a pipe next to it (but not
connecting) was also full of water
Only tested under "classic" flowing logic mode.
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
This also enables proper handling of a valve or sensor turned vertically.
Some objects have rotation disabled entirely (as flipping them over/around makes
When a valve is rotated, it is turned off automatically, to work around a glitch in
the rotation code.
The table lookup will fail if node.param2 is outside [0-3] which
is easily possible since there are several ways to modify param2
values of nodes. Force truncating param2 to always be 0-3 before
using it in a table lookup.
