10 * Clear the four quadrants of the canvas as follows:
11 * +------+------+
12 * | red |green |
13 * | | |
14 * +------+------+
15 * | blue |white |
16 * | | |
17 * +------+------+

19 * This is for checking that we're getting the right colors when
20 * we ask for them. This combined with the Orientation test assure
21 * that we are getting the correct colors in the correct places.
