Does anyone know any non-VCL GUI libraries for OpenGL or D3D? This question was asked over at Delphi3d.net and I realised that I didn't really know of any! :? The only one I know of just now is at Sulaco, but I want to do a quick stock-take.

If you have any links then please share them...

P.S. I'm writing my own, and I'm sure that many people have been in the same situation before.
