I believe this could avoid at least one copy of the canvas's buffer from the graphics card to the CPU and back again - which might be useful for animation performance? Also, yeah, it's a more "obvious" way of doing this - instead of rendering to an offscreen canvas and converting that to an image, just render to the right place in the first place.
