          /**

v.s.

// 2. horizontal flip
image(canvas, 0, 0, canvas.width, canvas.height,
canvas.width, 0, 0, canvas.height);

would still mean for me that you copy a empty rectangle

// sorry for my beginner scale test , but i needed a easy example,
and your title sounds like: SCALE() not working / mirroring
the title should be more like

IMAGE() not working as expected.
