wayland: reworked resizing

This fixes 2 bugs:
 * Resizing very fast breaks the aspect of the window and the width and height
   don't match with the video anymore
 * Pressing 'f' for fullscreen very fast can overwrite the backup variables for
   the previous width and height.

Also includes a better aspect calculation with fluid resizing.
