[PATCH weston v2] 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.

I see what you're saying now, thanks Ander. Changed 
weston_output_update_zoom() to accept wl_fixed_t types
so it's clear how it's meant to be used.
