I'm not sure that would be workable in a worker for SVG, for the same 
reasons that responseXML is not available in workers: it involves DOM 
elements.  Unless the SVG rasterization happens on the main thread under 
the hood and the raster data is then sent over to the worker.  This 
might have ... surprising performance characteristics.
