Script Widescreen

#==============================================================================
# ■ WScreen
#------------------------------------------------------------------------------
# 　By Selwyn, Widescreen effect script
#  released the 1st of February
#
# This script allows to give some cutscenes a 'widescreen' effect.
#
# The script is off by default (when you first start the game).
#
# By default, when the widescreen mode is turned on, it hides one tile at the
#  top of the screen and one tile a the bottom.
#
# By default, the transition_speed is 3, you can change this value just a
#  few lines below
#
# To turn the script on, put 'WScreen.turn_on' in a call script command of
#  an event. Turn it off with 'WScreen.turn_off'
#
# To change the number tiles hidden in widescreen, use the following function
#  in a call script command of an event :
#  'WScreen.size = NUMBER'
