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).

This could be fixed on Sun's side once we fix bug 14015.

There is copy on Wayback Archive: https://web.archive.org/web/20071016141137/http://research.sun.com:80/projects/lively/index.xhtml

But it is loading empty in Chrome Canary 120, Firefox Nightly 120 and Safari Technology Preview 180.

Since we don't have reproducible test case for this 2007 bug, I would rather close it and focus on newer ones.

So marking this as 'RESOLVED CONFIGURATION CHANGED'.
