Rasterise the SVG canvas, and use getPixel exactly as you do on a Raster image. The existing draft doesn't mention much about what the X and Y longs refer to in getPixel I guess the intention is that it's raster pixel in the co-ordinate space of the image, otherwise you'd have the same sampling problems as with Vector formats I guess. In which case all you need to define is the size (so whole units in the user coordinate space maybe, or in terms of pixel for example.) of the image to be rastered before being able to call getPixel on it.
