/**
* @file sprites.h
* This file contains all sprite-related enums and defines. These consist mainly of
* the sprite numbers and a bunch of masks and macros to handle sprites and to get
* rid of all the magic numbers in the code.
*
* @note
* ALL SPRITE NUMBERS BELOW 5126 are in the main files
*
* All elements which consist of two elements should
* have the same name and then suffixes
* _GROUND and _BUILD for building-type sprites
* _REAR and _FRONT for transport-type sprites (tiles where vehicles are on)
* These sprites are split because of the Z order of the elements
* (like some parts of a bridge are behind the vehicle, while others are before)
*
*
* 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 abbreviations when their meaning is clear or
* the length of the enum would get out of hand. In that case EXPLAIN THE ABBREVIATION
* 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 doesn'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.
*
* @todo Split the "Sprites" enum into smaller chunks and document them
