Sadly, Plasma ignores blurring of SVG objects and masks, which breaks shadows and some other features of original Oxygen SVGs. That could be solved by rendering PNGs at multiple resolutions, but for now I don't want to invest the time to make it work (original Oxygen already has this thing implemented, so I wouldn't be reinventing the wheel, though).
