3262 - Some SVG Elements, pixel and percent positioning

SVG Elements can be specified in terms of absolute co-ordinates of fixed pixel positions - and these two images which are generated from the same SVG file illustrate how that difference can be used to generate an image which varies as the window in which is called up - but it varies only in parts. ....
