Subject: [PATCH] video: Check video backend initialization when querying the
grabbed window
SDL_GetGrabbedWindow() can be called when the video system is uninitialized, and, since there is no window parameter, _this must be checked for validity to avoid a segfault.
(cherry picked from commit be82f316c4745d4cf0f8c0a5e37f5390beed9542)
