/*
	All sprites which are described here are referenced only one to a handful of times
	throughout the code. When introducing new sprite enums, use meaningful names.
	Don't be lazy and typing, and only use abbrevations when their meaning is clear or
	the length of the enum would get out of hand. In that case EXPLAIN THE ABBREVATION
	IN THIS FILE, and perhaps add some comments in the code where it is used.
	Now, don't whine about this being too much typing work if the enums are like
	30 characters in length. If your editor doen't help you simplifying your work,
	get a proper editor. If your Operating Systems don't have any decent editors,
	get a proper Operating System.
