Add double blur value into 'feGaussianBlur'

[jasomdotnet]

You have something like this, now:
<feGaussianBlur in="SourceGraphic" stdDeviation="10"/>
Double the 'stdDeviation' value like this. You get better blur effect:
<feGaussianBlur in="SourceGraphic" stdDeviation="10 10"/>

See this svg source code.
