Determines whether entities are loaded into video memory at creation time, or
when they are visible;
also determines the behavior of cloned enties.
Preloading entities at creation increases
the level loading and entity creation time, but prevents a little 'jerk' when an entity becomes visible
the first time.
1 - Don't preload entities (default).
2 - Preload all entities placed in the level.
3 - Preload all entities placed in the
level or created by ent_create.
Pre-calculate the entities' environment light. This increases the entity creation time, but makes the entity appear faster when it's visible the first time. A7.79
Keep cloned entities in the level cache. This speeds up ent_clone and ent_remove of cloned entities, but consumes more nexus and video memory, and increases the level change time when many entities were cloned. A7.79
In the release version, load entities and levels only from a resource, not from an external file. This prevents users from replacing entities with their own files.
preload_mode = 2+4; // preload level entities and precalculate their environment light.
