Macros
#define	TILEMAP_FLAG_WEATHER_MASK 0x0f
	Bitmask indicating flags that determine TILEMAP weather.

#define	TILEMAP_FLAG_WEATHER_SNOW 0x01

#define	TILEMAP_FLAG_WEATHER_RAIN 0x02

#define	TILEMAP_FLAG_EDITABLE 0x10

#define	TILEMAP_ERROR_BLOCKED -40
	Return value indicating movement is blocked by terrain.

#define	tilemap_get_tile_id(t, x, y) (((t)->tiles[((y * TILEMAP_TW) + x) / 2] >> (0 == x % 2 ? 4 : 0)) & 0x0f)
	Get the TILEMAP::tileset index for the tile at the given coords.

#define	tilemap_tile_get_image(tt) ((tt)->image_cache_id)
	Get the pointer to the sprite graphic to use for a ::TILEMAP_TILE.

#define	tilemap_is_dirty(x, y, map) (((map)->tiles_flags[((y) * TILEMAP_TW) + (x)] & TILEMAP_TILE_FLAG_DIRTY))

#define	tilemap_set_dirty(x, y, map) (map)->tiles_flags[(y * TILEMAP_TW) + x] \|= TILEMAP_TILE_FLAG_DIRTY;

#define	tilemap_unset_dirty(x, y, map) (map)->tiles_flags[(y * TILEMAP_TW) + x] &= ~TILEMAP_TILE_FLAG_DIRTY;

Functions
int16_t	tilemap_load (const char map_name, struct TILEMAP t)
	Load tilemap with map_name into the given TILEMAP and prepare it for running in the engine.

int8_t	tilemap_collide (uint8_t x, uint8_t y, uint8_t dir, struct TILEMAP *t)
	Detect potential collision between a MOBILE and TILEMAP tile with blocking flags.

void	tilemap_advance_tile_id (struct TILEMAP *t, uint16_t x, uint16_t y) SECTION_TILEMAP
	Increment the tile_id on the specified tile coordinates. Useful for editing TILEMAP.
