:) Been a long time coming, I'm very happy with the framework as it's looking
at present.  It would be good to be very confident about the SVG implementation before 
I really start pushing foward using the thing.  (We've got applications for this work 
at the company which will be hard to change once they get into productive use)

My implementation throws exceptions and dies on loading any unsupported element at present.  
This means it can't load some of the test suite examples it cannot render, but also as
for example the <desc/> element is not implemented, it can't load any of the test suite
examples at present.  (though <desc/> isn't needed to render them of course)

Also my implementation is a bit fussy about syntax, spaces in comma seperated attribute lists 
throw it for example.  This is something I want improve anyway.  The test suite examples have a 
wide range of formats for colour settings (pretty much all that's in the SVG spec), the framework 
only supports named colours and #RRGGBB syntax at present (again something I want to improve)

Cool, sounds easy.  I could provide an application which loads a file specified to it as a parameter, 
that would be pretty easy.  My example SVG view app has a file load dialog already too.

Sounds good.  Send me the results file any time, I'll be keen to see the format.  I'll provide an application
to render the SVG test suite examples when ready
