Calculate the aspect ratio in vo_config, when we get the window size and in the inside the resize function we calculate the aspect ratio of the output in order to determine if we have to change the height or the width of the video. If the ratio of the output is bigger than the ratio of the video then we have to set the width accordingly and if the ratio is smaller we change the size. But only if no resize edges are passed, because this indicates that we want to change the windows state instead of just a simple resize and the video should not grow bigger than the requested size.
