------- Additional Comments from Nikolas Zimmermann <zimmermann at kde.org>
Attaching patch which reworks pattern handling to actually work in all
patternUnits/patternContentUnits combinations. Fixes quite some testcases:
coords-units-01-b.svg (also work with run-safari now, under any zoom level)
pattern-in-defs.svg (pattern buffer allocation now clipped against target bbox)

js-update-pattern.svg (live update really works now! all repainting is done
properly)

Also get rid of SVGResourceListener, and the whole resourceNotification()
logic.
This also fixes gradients causing objects to redraw twice.
