Basic Window Resizer

#Basic Window Resizer v1.1
#----------#
#Features: Allows you to resize the window to whatever size you like! (This is not
#            like Graphics.resize, this will scale to fit)
#
#Usage:   Script calls:
#           Window_Resize.r(width, height)     - Self-explanatory
#           Window_Resize.f                    - fits the game window to monitor size
#           Window_Resize.full                 - switches to full screen unless already fullscreened
#           Window_Resize.window               - same as full but opposite
#           Window_Resize.toggle               - toggles between full and window
#
#No Customization
