Well the main extension i added is the possibility to render to a texture using the extension WGL_ARB_RENDER_TEXTURE which works pretty well now.
I also coded some tests about Cg Vertex Programs. Those programs work quite well but are not yet enough flexible to be commited.
These are interesting things you are working on; however, they are also part of some core changes we have been planning for GEM. Because of this, I don't think either of your two developments should be committed now.
Specifically, render-to-texture is part of the multiple windows and targets, and I think we will look at pBuffers to help achieve this. As for shaders, I would prefer not to use Cg for two reasons: one it's not part of ARB OpenGL, and not equally supported between platforms or vendors. Also, I think GLSL has potentially a superior architecture, although it might take ages for it to even be implemented fully on all three of GEM's target platforms. Both of these projects are still really in the planning stages, and various people are experimenting with potential solutions.
You should become a developer since you are interested in working on advanced features, and also seem to be working on Windows. It would be good to have someone to help out with the render targets and shading, and you will get some help with figuring out GEM's internal architecture.
