Remarks
The canvas target must first be chosen with CANVAS_Attach.
CANVAS_Scale lets you define your own world coordinate system for subsequent statements.
The custom coordinates remain with the canvas target until CANVAS_Scale is repeated, or the target is deleted.
World coordinates may be values, with the only requirement that x1 not equal x2, and y1 not equal y2. If either is equal, the statement is ignored.
If x2 is greater than x1, coordinates grow to the right. Otherwise, they grow to the left.
If y2 is greater than y1, coordinates grow downward. Otherwise, they grow upward.
