* File: z_obj_grass_unit.c * File: z_obj_grass_unit.c
* Overlay: ovl_Obj_Grass_Unit * Overlay: ovl_Obj_Grass_Unit
* Description: Spawner for circular patch of grass * Description: Initializes a pattern of grass to be passed to an ObjGrass instance.
*
* ObjGrassUnit instances are intended to be spawned from room data so that just one ObjGrass instance manages the grass
* for that room. When a room with ObjGrassUnit spawns loads, it allocates ovl_Obj_Grass_Unit and creates N instances of
* ObjGrassUnit. The first instance processed initializes sGrassManager, then all instances live on that cycle pass type
* and position data to that ObjGrass instance before calling Actor_Kill. Since ovl_Obj_Grass_Unit uses
* ALLOCTYPE_NORMAL, it is deleted and loses the reference to the newly created ObjGrass. This allows for ObjGrassUnit
* spawned in a different room to be associated to a new ObjGrass instance.
