Window resize does not preserve aspect ratio

[der_julian@…]

With a X11 window manager that does not (or cannot) support the aspect hint, such as "Tiling&Tabbing" window managers like wmii, mplayer behaves oddly when resizing the video window: It always fits the video into the whole window and thus distorts the aspect ratio. Personally, I cannot think of any use of that "feature". A correct way to handle this is to pad the video with black bands to fit the window while keeping the video's aspect ratio.

On a side note: An X11 application should obey the window size the window manager provides.
