[PATCH weston v3] Convert wl_fixed_t to int in weston_output_update_zoom().

[Scott Moreau]

This way, we don't have to use wl_fixed_to_int() for each
call to weston_output_update_zoom(). It accepts wl_fixed_t
types and converts internally.
---

Changed arg names and declare x/y as int32_t types since we
treat wl_fixed_t as it's own type.
