However, skia in *http://code.google.com/p/skia/source/browse/trunk/src/effects/SkBlurMaskFilter.cpp* (MAX_RADIUS) is limiting it to 128? For performance reasons, wouldn't it be better to follow skia model here and limit the radius values even more? It seems to me that values greater than 128 are both computational intensive and unlikely to be used in practice.

I agree, I think we can use deviation instead of radius and do it inside the FEGaussianBlur object that way, we can use 50 for instance which is a radius of 94.5 aprox. I think mozilla is using 25, at leas in the canvas.
