# ** Battlebacks VX
#------------------------------------------------------------------------------
#    by DerVVulfman
#    version 1.2

#
#  INTRODUCTION:
#
#  This system reintroduces the use of 'Battleback' graphics into your pro-
#  jects, something that was sadly lacking in tbe RPGMaker VX system.
#
#------------------------------------------------------------------------------
#
#  SCRIPT CALLS:
#
#  There's only one script call that you need to know.
#
#  --Changing Battlebacks--
#  Given that this system allows you to use 'Battlebacks, you may find a need
#  to 'change' the battleback in-game. Unfortunately, this can't be done with
#  a pre-rendered map event, so I had to make a script call:
#
#           $game_system.battleback = "filename"
#
#  The filename is whatever is stored within the folder that you have speci-
#  fied in the configuration section (in the BATTLEBACK_DIR value).
# 
#------------------------------------------------------------------------------
#
#  SCRIPT PLACEMENT:
#
#  As a core/re-insertion script, it returns the classic battle backgrounds
#  that many users became used to with other RPG gaming systems.
#
#  If this script is being used  with any other script that alters any dis-
#  played effect or any system in the battlesystem's spriteset window, then
#  those scripts will most likely be placed BELOW this script  as they will
#  most need access to the revised battle viewport.
#
#------------------------------------------------------------------------------
#
#  EDITS AND MODIFICATIONS:
# 
#  This system Aliases the following methods:
#  * initialize                     (Game_System)
#  * create_battleback              (Spriteset_Battle)
#  * create_battlefloor             (Spriteset_Battle)
#
#  This system adds the following methods:
#  * battleback                     (Cache)
#
#------------------------------------------------------------------------------
#
#  THANKS:
#
#  To Fantasy at RPG RPG Revolution for noticing a bug when using the 'Battle
#  Test' feature.
#
#------------------------------------------------------------------------------
#  TERMS AND CONDITIONS:
#
#  Free to use, even in commercial projects.  Just note that I need some form
#  of due credit... even a mere mention in some end titles.

#==============================================================================
# ** Cache
#------------------------------------------------------------------------------
#  This module loads each of graphics, creates a Bitmap object, and retains it.
# To speed up load times and conserve memory, this module holds the created
# Bitmap object in the internal hash, allowing the program to return
# preexisting objects when the same bitmap is requested again.
