/* TRON element is meant to resemble a tron bike (or worm) moving around and trying to avoid obstacles itself.

* It has four direction each turn to choose from, 0 (left) 1 (up) 2 (right) 3 (down).

* .tmp bit values: 0 tail , 1 head , 2 no tail growth , 4-8 is direction , 16 is wait flag

* .tmp2 is tail length (gets longer every few hundred frames)

* .life is the timer that kills the end of the tail (the head uses life for how often it grows longer)
