Has anyone looked into using AGG (http://www.antigrain.com) as the low level back-end? AGG itself seems very low-level in some places, which might cause problems but it seems very functional. I searched this list and found another reference that said it might be good for being able to add the SVG filter support. Personally, I would love to finally have that functionality.
I made a real quick look at the code and it looked nice and seems flexible.
In my limited testing I found that it was extremely fast.
It doesn't have much in the way of SVG support though. There is an example SVG viewer but barely has any functionality. I suppose Inkscape would just keep its current SVG stuff anyway.
I was just wondering if anyone had looked into it and if they found any serious issues. I assume Inkscape switched from librsvg to livarot for some good reason and I'm just wondering if AGG was a consideration.
