; Pacman movement and collision rules
; * Pacman moves in the direction he was told until stopped by a wall
; * If the player tells Pacman to change direction but there is a wall there,
;   Pacman's direction does not change
; * Turning a corner is funky:

; "Whenever Pac-Man makes a pre-turn or post-turn, his orientation changes, and he starts to
;  move one pixel in his new direction for every pixel traveled in his old direction, effectively
;  doubling his speed as he moves at a 45 degree angle. Once he reaches the centerline of the new
;  direction's path, he starts moving purely in that direction and his speed returns to normal."
; The simplest way to implement this appears to be to treat turns as having a "fudge factor" -
; Pacman enters a state where he changes direction _and_ is being pulled towards the center of
; the track. (The "post-turn" correction means we can't simply treat this as the corners having
; their edges filed off!)
; I think Bomberman actually does this too
