MEIKYUU_ORIENTATIONSconstant

WHICH WAY UP A MAZE IS LOOKED AT. A tall maze is made to be played upright on a phone and wants to lie down on a wide screen; a wide one the other way. Turning is presentation only: the maze, its cells and the line drawn through them stay as they were made (the logical orientation), and the board draws them a quarter turn counter-clockwise, so the maze's top is on the left, its left at the foot, and a finger's path over the picture is carried back into the maze before anything is decided. A line stored as its steps (lineToSteps) therefore replays the same on a board turned either way, which is what lets a person start a level on a phone and finish it on a desk.

The turn is a quarter turn counter-clockwise: the logical point (x, y) is shown at (y, -x), a rotation of -90 degrees in SVG's terms.
