    I think that CSS3 would be a better target for this, and thus it 
should probably be addressed on the W3C www-style mailing list:

    http://lists.w3.org/#www-style

    Perhaps something like this would do...

HTML:
| <div id="special-shape"><!-- Contents --></div>

CSS:
| #special-shape {
|   background-image: url(special.png);
|   crop: background;
| }
