# 2012.11.14 - Started and Finished Script.

#==============================================================================
# ¥ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script provides a Faces-cache for default Window_Base, which enhances
# a little performance for Windows.
# 
#==============================================================================
# ¥ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ¥ Materials/‘fÞ but above ¥ Main. Remember to save.
#
#==============================================================================
# ¥ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
# This script will not work with a custom draw face method.

# ¥ Editting anything past this point may potentially result in causing
# computer damage, incontinence, explosion of user's head, coma, death, and/or
# halitosis so edit at your own risk.
