★Usage★
This script uses overwrite function, and thus if you decide to use the script, put it above all your custom scripts for the best compatibility cases (or edit it yourself so that you could put it anywhere in your script slot)

●In the enemy Note box, put this note tag <scale>.
●If you use <invert> inside the enemy Note box,
the enemy graphic is flipped horizontal. Can be used together with scaling.

Example) <scale 1.5> in the Note box for slime of enemy ID1
　　The slime graphic is multiplied by 1.5 during battle.

★Overview★
Scale / Invert effect can be used without directly editing the enemy graphics.

★Note★
Please pay attention to performance of large enemy graphics.
If you use multiple enemies, they will overlap unless you adjust their position.
Due to how redefinition is used, there may be script conflicts.
