# Yanfly Engine RD - Display Flipped Picture
# Last Date Updated: 2009.03.30
# Level: Easy
#
# RPG Maker VX's event editor lacked the ability to flip pictures for some
# reason. With this script, that should be doable again while staying in the
# confines of the editor itself. This will save you the need to produce extra
# copies of a profile cut-out in its mirror form.
#
#===============================================================================
# Instructions
#===============================================================================
#
# There's a switch designated to picture flipping. By default, it's switch 61.
# If you're already using that switch for something else, just change the value
# below to reflect which switch you'd like to dedicate picture flipping to.
#
# If this switch is ON, the pictures shown and moved following it will flip.
# If this switch is OFF, following pictures will be shown unflipped like normal.
#
#===============================================================================
# Updates:
# ----------------------------------------------------------------------------
# o 2009.03.30 - Started script.
#===============================================================================
#
# Compatibility
# - Alias: Game_Picture, initialize, show, move
# - Alias: Sprite_Picture, update
