OK, I'm looking at the Wiki and I'm confused. I'm using the JSVGCanvas.
>From the Wiki:
"If you are using the JSVGCanvas it does this when you associate an
SVGDocument with the canvas."
It sounds like that I'm using the SVG and CSS DOM interfaces already
then? I also have a GVTTreeRendererAdapter that listens for
gvtRenderingCompleted.
My element definitely has a "fill" associated with it.
Here's my stack trace. The offending line is the SVGPaint declaration:

This also reminds me that if you are asking about the fill on an
SVG element that is a child of a non-SVG element (say a custom
element in a custom namespace) then the CSS cascade won't be active
in that 'branch' of the DOM (partially because it's unclear how
the non-SVG element should effect the CSS cascade).
