#ifndef SPRITES_H
#define SPRITES_H

/** @file sprites.h
 * This file contails 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
 * SPR_CANALS_BASE is in canalsw.grf
 * SPR_SLOPES_BASE is in trkfoundw.grf
 * SPR_OPENTTD_BASE is in openttd.grf
 *
 * 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 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.
 *
 * @todo Split the "Sprites" enum into smaller chunks and document them
