There are two remaining bugs:
- Handling of transparent pixels in
- Generation of frames from canvas that are not in the DOM tree can be erratic or freeze (https://jsfiddle.net/0b3dqxeg/).

Let's focus this particular bug on transparent pixel handling.
I filed https://bugs.webkit.org/show_bug.cgi?id=240380 to jeep track of not in the DOM canvas.
