Inkscape vector image editor

Today while I was watching TV, I was learning a new - well, new to me - freeware vector editing program, Inkscape.   It creates SVG images, which are just about starting to be a useable,supported graphic format for web pages.     At the moment, graphics on web pages are mostly png, jpg and gif format.  All of these are bitmap formats - ie, the code behind them specifies the colour of each pixel, or each line of pixels.
