A common standard would be useful, but OpenVG doesn't look like "ready soon". On the declarative side, there's also SVG..
Seems I've got to qualify that remark somewhat - apart from some commercial/closed-source implementations, there is also a open source ANSI C one (implemented on top of OpenGL, so it isn't quite the same as direct OpenGL hardware support, but it offers the same API and might be a good target for a Haskell binding..): http://ivanleben.blogspot.com/2007/07/shivavg-open-source-ansi-c-openvg.html Also, an OpenVG backend for Cairo, which seems to have so many backends that it might be the safest user-level choice? http://lists.cairographics.org/archives/cairo/2008-January/012833.html http://lists.cairographics.org/archives/cairo/2008-January/012840.html Claus
