* @help This plugin allows the use of weapon sprites that
* do not conform to the usual 96-pixel pattern width and
* 64-pixel pattern height. Weapon patterns still need to
* be laid out in columns that are six weapons tall
* and three patterns wide. Weapons1 and Weapons2 images
* still need to have 2 weapon columns and Weapons3 is
* still only 1 column.
