 * Basic test for axis locking behaviour.
 * - Load page and verify it draws
 * - Drag page upwards 100 pixels at a 5-degree angle off the vertical axis
 * - Verify that the 5-degree angle was thrown out and it dragged vertically
 * - Drag page upwards at a 45-degree angle
 * - Verify that the 45-degree angle was not thrown out and it dragged diagonally
