While right now svg.el seems to have more features, it isn't
particularly well suited to displaying things quickly.

In fact, my own bad experiences with using svg.el to draw rapidly
changing information inspired me to begin working on this.

In the future, I hope that canvases also become more flexible than
svg.el.  A nice goal would be to have everything cairo has.
