Snap Gradients with Percentage offset values

SampleOutput

var g = s.gradient("r(145,331,38)#fff:0%-rgb(75,75,123):50%-rgb(68,68,68):100%");
console.log(g.toString());
Output:
<radialGradient cx="145" cy="331" r="38">
    <stop offset="NaN%" stop-color="#ffffff"/>
    <stop offset="NaN%" stop-color="#4b4b7b"/>
    <stop offset="NaN%" stop-color="#444444"/>
</radialGradient> 

var g2 = s.gradient("r(145,331,38)#fff:0-rgb(75,75,123):50-rgb(68,68,68):100");
console.log(g2.toString());
Output:
<radialGradient cx="145" cy="331" r="38">
  <stop offset="0%" stop-color="#ffffff"/>
  <stop offset="50%" stop-color="#4b4b7b"/>
  <stop offset="100%" stop-color="#444444"/>
