[Bug 11517] Since context.putImageData() does not handle compositing, another set of methods, maybe context.drawImageData(), should be created to allow ImageData objects to be drawn onto the canvas in the same fashion as Image objects.

If you want to composite a whole canvas onto another canvas, you can just use
the first canvas as an argument to drawImage().  If you want to composite a
portion of a canvas onto another canvas, you can first use putImageData to draw
the portion onto a *third*, appropriately sized, canvas, and then use drawImage
with the third canvas.
