Max Resolution Addon RMVXA Script

#==============================================================================
# Some stuff to enhance Max Resolution Script. Put this script below it.
# By Black Mage
# Version 1.3
#
# This script required Max Resolution Script to function properly. You can get
# the script at:
# https://pastebin.com/FyLyMzis
#
# You can add Tsukihime's Map Screenshot Script on your project to have a
# better transition when changing into a higher resolution. The original script
# function will be disabled, but you can turn it on through a setting below if
# you wan to use it.
# You can ge the script at:
# http://himeworks.com/2013/02/map-screenshot/
#
# -----------------------------------------------------------------------------
# What this script actualy do?
#
# Well, there's this black bar occupying the window if you change into a higher
# resolution from map. When you access the menu, and back to the map again, the
# black bar is gone, and you can freely change the resolution back and forth
# without have to worry that the black bar will appear, unless you're changing
# into a new higher resolution compared to the last resolution where the black
# bar appeared.
#
# This script run a dummy scene to simulate the menu access in order to fix the
# black bar problem when a higher resolution change is happened.
# -----------------------------------------------------------------------------
# Note that the Max Resolution Script has a memory dependancy. If somehow your
# project crashes when doing a playtest, just do some other stuff and hope that
# when you playtest and changing resolution again, nothing wrong happened. XD
#
# Don't immediately playtest when a crashes occured!
# -----------------------------------------------------------------------------
# Stuff that's not fixed yet from Max Resolution Script:
# If you're on a big map, and you change resolution from the right corner of
# the map, your map camera might shot a wrong part of the map for a few seconds,
# or until you move your character to left for a bit.
#
# I'm not sure when I'll fix this in the future. If you somehow able to fix it,
# let me know.
