wm4 67fcdcd8a3 win32: different method to force window aspect ratio
The code used WM_WINDOWPOSCHANGING to force an spect ratio. This didn't
behave well if the left/top window borders were used for resizing.
Resizing with these borders changed the screen position of the right/bottom
as well, which is unintuitive and annoying.

Use WM_SIZING instead. Unlike WM_WINDOWPOSCHANGING, WM_SIZING knows about
which border is being used for resizing and can act accordingly.

Note that the calculated window size doesn't necessarily match with the
size mplayer calculates, but this problem exists on x11 as well.
