Re: Looking for SVG that was/is slow in Firefox

Hi Jonathan, I notice that the speed of the js in Firefox has improved
recently. I had some browser conditional on the box2d example (hokusai
physical attraction) at http://vectorshapes.com because there was too much
lag in FF, removed that tonight and is running much smoother which is great!

+1 for James' suggestion that the missing feImage support is important. As
an example, the tiltshift app at http://vectorshapes.com/0/#tiltshift relies
on this filter primitive for alpha masking etc.

Cheers
Pete
