The development version 0199 is opengl2 (but is now opengl), however lots of stuff is broken, many libraries won't work with it but it might just do what you want (otherwise I think there is hell of lot to do before version2 gets released).

How about now? ;-)

It's probably getting close.  They're working hard on it.

The compatibility has gotten better as far as libraries for the ones I've tested.
