`SDLTextureYUYV` uses `SDL_PIXELFORMAT_YUY2`, which is a single plane format. To support other single plane formats, replace `SDLTextureYUYV` with `SDLTexture1Plane` that can be instantiated with an arbitrary SDL pixel format and that uses `SDL_UpdateTexture()` to update the texture using exactly a single plane.
