# ** Drago - Tilemap Effect
# Version : 1.02
# Author : LiTTleDRAgo
#==============================================================================
#
# Introduction : 
#
#     Based from Tilemap tone changer script, this script adds some effects to 
#     the tileset bitmap such as invert or grayscale
#
# Example :
# 
#   Script : 
#      add_tilemap_effect(:invert!)    # invert the tilemap
#      add_tilemap_effect(:grayscale!) # after inverting, grayscale the tilemap
#      add_tilemap_effect(:hue_change, 120) # change the hue by 120
#      add_tilemap_effect(:brighten!)  # brighten the tilemap by 10 degree
#      add_tilemap_effect(:darken!)    # darken the tilemap by 10 degree
#
#  Option available : :invert!, :grayscale!, 
#           :hue_change (with argument)
#           :brighten! (with / without argument) default is 10
#           :darken! (with / without argument)   default is 10
#
#   Script : 
#      clear_tilemap_effect            # clear all effect
#
# Note : 
#
#  -  Not recommended to use in map with large tileset bitmap.
#  -  The first time you add the effect, game will froze for a while to create
#     a cache, you can found the cache file in :
#       C:\Documents and Settings\[user]\Application Data\Drago\Tileset
#       C:\Documents and Settings\[user]\Application Data\Drago\Autotile
#     or
#       C:\Users\[user]\AppData\Roaming\Drago\Tileset
#       C:\Users\[user]\AppData\Roaming\Drago\Autotile
#  -  To revert back the tileset, you must use "clear_tilemap_effect"
#  -  Recommended to use it with WhiteFlute's Bitmap EX
