Yeah, I was in a hurry. Sorry.

Actually canvas size is specified which gives you your right and
bottom margins. However it could also be done with a single
right-margin/bottom-margin pair that would look to the rightmost and
bottommost regions. Including this simple value get around the need
for right and bottom. Otherwise it's pretty much correct.

Either bottom/right padding would need to be implemented or
width/height needs to be implemented, but only for the canvas. I
prefer width/height because it reduces the number of concepts needed.

Yeah, I forgot to thank Andrew for the basic idea. He has been so
persistent that it's been in my mind for awhile now. He had
implemented it in his browser, but people kept saying it couldn't be
done. So I guess percentage free space was keeping me occupied.
