This small change only allows single canvas elements as kernel input. They have
the exact same properties and use cases as html images, bit if you need to use
a canvas directly it is more efficient than converting it to an image first.
Because canvas and image have a very similar API in webGL it did not seem to cause any issue. However, I ran into troubles running your test cases on my machine (unmodified source) so I can not confidently say it has passed.
