Of it, the backends read the EFB scale, now passed as the backbuffer scale; GLContext::Create tested for libretro, its only context; and the controller interface kept a render window that is always null. The video backends' Initialize, InitBackendInfo and PopulateBackendInfo, Core::Init, EmuThread and StartEmuThread, BootCore and the controller interface lose the parameter; PrepareWindow, ChangeWindow, the window change refresh and the Vulkan instance's surface extensions go, as nothing presents but the frontend.
