A complex logo I'm rendering shows artifacts between the different shapes. 
These are not gaps in the artwork, but aliasing artifacts.

I found a good solution for removing these artifacts, being to mask the object and apply a very slight gaussian blur (feGaussianBlur) with a low stdDeviation value (0.125). 

Chrome, firefox and even IE display it well. Desktop Safari (8.0) however seems to always treat the blur as if the value was at least 1px (or so it seems to be) making it too blurry to be an acceptable representation of the logo.

Is there a way to make safari support a value between 0 and 1?
