> SVG large rect with shadow
> 
> Addition of a shadow to a large rect (x=0,y=0,height=100,width=2147483647) causes it to no longer render.
> 
> Platform: Chromium (most recent build)
> 
> Steps to reproduce: Load the attached file, rect-with-shadow-maxing.svg in Chromium.
> 
> Expected output: A purple rectangle at the top of the viewport, with a grey shadow underneath. The rect will fill the width of the viewport.
> 
> Actual output: No rectangle or shadow is rendered.

I tried using floats instead of ints for storing the 4 intermediate shadow values, then the following addition is all done using floats and the .svg shows up fine. I doubt there would be performance problems with such a change, and I guess shadows are rare in typical svgs, so do you think that would be good enough to fix this bug? I can make a patch for that, but the replacement is so simple that I think you can imagine it easily :) Let me know what you think.
Cheers,

Rob.
