Bug 1348430 - Part 1. (Main) Correct value pass to nsFilterInstance::PaintFilteredFrame in nsSVGUtil. r=mstange

Browse Source 
There are two places that use nsFilterInstance::PaintFilteredFrame. One is
nsSVGIntegrationUtil::PaintFilter, we do take care of it in bug 1224207.
Another path is at nsSVGUtils::PaintFrameWithEffects, apparently I missed that
path while working on bug 1224207.
