Hm. What are the prerequisites to using the SVGLocatable transforms?
Should I be able to add an element and transform it like this?

   // ...load SVGDocument...
   Element g = svgDocument.createElementNS 
   someElement.appendChild( g );
   SVGMatrix xform = SVGLocatableSupport.getCTM( g );
   xform.translate( 42.0f, 42.0f );
   // ...proceed to rendering...

This produces a NullPointerException in the anonymous SVGMatrix  
implementation by SVGLocatableSupport.getCTM() - the 'g' I created  
doesn't have an SVGContext yet. I suppose I'm skipping essential  
steps... Do I need to build a GVT first, or do some sort of update?
