Using conrod with opengl_graphics and sdl2_window?

[GGalizzi]

The guide mentions support for both, though I find nothing in the documentation/source.

I'm creating my window with sdl2_window and drawing with opengl_graphics, I managed to create the UI and a Text primitive following the "all_piston_example" found here, making the necessary changes. But I can not figure out how to draw! The one backend that seems like the one I might want is piston, but I of course get an error that the types wont match since the Context I have is from graphics::Context, not conrod::backend::piston::draw::Context. And the Graphics I have implement graphics::Graphics, not conrod::backend::piston::draw::Graphics.

I'm kinda new to Rust so I might be missing something.

Any help is appreciated, thank you!
