scaling: always round the scaling factor when converting to int

Browse source 
* In all calls to wl_subsurface_set_position()
* (wp_viewport_set_destination() already does this)
* Whenever we use the scale to calculate margins (search box,
  scrollback indicator etc)
* Since the scaling factor is stored as a float (and not a double),
  use roundf() instead of round()
