add comment about the rect coordinates, for future historians?

Done.

interesting it goes to 0, what is the ownership model? if it is explained
somewhere else. The browser makes a copy I am guessing?

It's not explained anywhere else. I think they have to make a copy to marshal
the image to Java, so it's assumed that the image is no longer needed. I put a
comment.
