macosx: fixes aspect ratio / crop functionality in some cases

With this commit the mentioned features result in an actual change, when we are in fullscreen or "macosx-video-autoresize" is false.
Furthermore, this fixes nasty flickering when normal window is changed in size while using this features.
Also this commit makes sure, that no window resize is happening in any case, when "macosx-video-autoresize" is false.
