My opinion is that at some point there should be specific guidance regarding the visual output.  At least for common sets of SVG code such as "basic" filter effects.  The test suites seem to do this to an extent with the PNG image comparisons, but we should eventually look into adding a more detailed and more automated visual QA process as part of the SVG unit tests.

I have only heard of a few such systems over the years.  Just as an example, this is a more recent one:

I imagine someone has probably even developed an Html5 canvas pixel-based image mapping/comparison tool, which could be used.
This next link is just an example of testing the drawing of pixes in Canvas for various browsers - http://jsperf.com/setting-canvas-pixel
