I did not, but when checking the website I found the proprietry
license of General Polygon Clipper (GPC) appalling.
Do you know how important gpc is for agg?
If it is not important, why is it still in there?

I cannot say, it would be interesting to see how wxWidgets people
thing about their drawing capabilities and what they plan in this area.
For www.skencil.org (former Bernhard Herzog's Sketch) I thought about Cairo.
Skenicl 0.7 uses libart, though this library did not continue as
strong as it started, so Cairo seems to be the future within Gnome.
In my personal list of what I want to do with Thuban the antialiasing
and transparency options are in the mid range. They look a lot nicer,
but functionality counts first for most users.
