OK, it looks like at least part of the problem is that the image is
no longer scaling down properly now it is in a canvas instead of a
vbox and it is no longer asking to be 100%. Not sure which is the
issue. So, my speculation is that neither math could possibly
position the image/swfloader properly, since both the image and the
swf are now larger than the canvas. Grrr.
