patch add SDL_ResetWindowShape function

For shaped window created by SDL_CreateShapedWindow the SDL_SetWindowShape function combined previous assigned shape with new. But I need reset assigned shape and set new. The only way I can do this is call SDL_SetWindowSize which clear bitmask of a shaper in a driver ResizeShape function, but unfortunately resizing shaped window set its position to x,y:-1000,-1000 and you need to set window position again. When a shape changes several times per second an application window start blinking and it looks awful. Adding function SDL_ResetWindowShape solves blinking trouble, example of such function for X11 driver is in included patch for SDL 2.0.8 version. Is it possible to add it in SDL library or may be there is another way to solve it. I did't find any example of animated shaped window.
