> Before this patch, window_size is always set to the source size
> In other word, -window_size option have no effect.

> To test :
> ./ffmpeg -f lavfi -i smptehdbars=hd1080 -c:v rawvideo -pix_fmt yuv420p
> -window_size 1024x576 -f sdl "SDL output with Custom Size"
>
> - 002 : Add option to set the position of the window
> the default behaviour doesn't change (set the position to undefined)
>
> To test :
> ./ffmpeg -f lavfi -i smptehdbars=hd1080 -c:v rawvideo -pix_fmt yuv420p
> -window_size 1024x576 -window_pos_x 30 -window_pos_y 100 -f sdl "SDL output
> With Custom size pos"
>
> - 003 : Add option to disable quit action
> Without this patch, the window can be close by the user
> if this new option is set, the window can't be close (by "close" window
> btn, escape, or "q")
> The default behaviour doesn't change
>
> To test :
> ./ffmpeg -re -f lavfi -i smptehdbars=hd1080:duration=10 -c:v rawvideo
> -pix_fmt yuv420p -window_enable_quit 0 -f sdl "SDL output Without Quit"
