SVG renders should not paint when obscured

I'm not sure how we could ever implement this efficiently.  But, ideally SVG
elements would not paint when they are fully obscured (and even better, clip
when they're partially obscured).  The desire for this behavior is made clear
when using something like: http://research.sun.com/projects/lively/index.xhtml
which has opaque "windows" which obscure other animated content (yet the
content still draws below it causing unnecessary repainting).
