Is it possible to make the opengl context current on other threads?

[saverioscagnoli]

I would like to process vertex data on a secondary thread, but every gl call fails unless the context is current on that thread. Since the video::Window has Rc<WindowContext>, it cannot be sent to another thread. How can i make the context current on another thread without the window?

Another thing (less important): is it possible to achieve something like glfw's render context (process sdl events on the main thread // calling opengl from another)
