Change SDL backend to restore the original GL context. This allows Qemu's virtio-gpu to support new virglrenderer async-fencing feature for Virgl contexts, otherwise virglrenderer's vrend creates a fence-sync context on the Qemu's main-loop thread that erroneously stays in-use by the main-loop after creation, not allowing vrend's fence-sync thread switch to this new context that belongs to it.

This offending scanout-disable race condition with a timer can be easily hit when Qemu runs with a disabled vsync by using SDL or GTK displays (with vblank_mode=3D0 for GTK). Refreshment of display's content shouldn't disable the active display. Fix it by keeping the scanout's state unchanged when display is redrawn. Reviewed-by: Akihiko Odaki Acked-by: Michael S.
