Just wondering if there's been any progress on this? I've been trying to make it work for the past couple of days and I've made *some* progress, but can't get anything to actually render to the control. I've managed to patch SDL so that it will create an OpenGL window in SDL_CreateWindowFrom (fully intend on making a blog post about this process as there's so little information online about how to do it!) and I'm calling CreateWindowFrom from Sdl2GraphicsContext. It seems to be handing back a valid window. I can create a context from it, no errors are thrown, the graphics mode seems to be correct, it's just that nothing renders to the control, not even the clear colour. I'm sort of at a dead end with this now, so I was hoping there was something obvious that needs to be implemented that I've overlooked. Any help would be great!
