title: How to change the background of an SVG in Codename One
body: <p>I have an SVG image and I have uploaded it successfully to Codename One and set it as icon to a SpanLabel using setIconMethod. But in the empty parts of the SVG, a black background is shown, and I want the background to be white. I tried to create a UIID with white background and then to use setIconUIID, but it did not work.</p>
  
  <p>How do I set the background for SVG images?</p>
