Update a window with OpenGL rendering.
void SDL_GL_SwapWindow(SDL_Window * window);
|window||the window to change|
This is used with double-buffered OpenGL contexts, which are the default.
On macOS, make sure you bind 0 to the draw framebuffer before swapping the window, otherwise nothing will happen. If you aren't using glBindFramebuffer(), this is the default and you won't have to do anything extra.
This function is available since SDL 2.0.0.
