One of my goals for 1.1.x is to improve the rendering quality of
the graphs created by rrdtool ... This means scalable fonts, anti-aliasing
true scalability ...

I can not see this being possible with libgd ... one way ahead
would be to employ imagemagick. http://www.imagemagick.org either
through its native drawing api

Another possibility is using svg http://www.w3.org/Graphics/SVG/Overview.htm8
together with an svg rendering library

* imagemagick is said to posess some svg rendering capabilities
* gnome nautilus contains librsvg
* there is also http://xml.apache.org/batik/ but this seems to be
  done in java entirely which does not sound like something we can

I find the svg route especially interesting as sooner or later we
can expect all browsers to be able to render svg directly ...

Any thoughts on this? Anybody knows of good svg rendering libraries
written in c ?
