Gets / sets composite caching. Composite caching draws this entity and all of it's children (and their children etc) to a single off screen canvas so that the entity does not need to be redrawn with all it's children every tick. For composite entities where little change occurs this will massively increase rendering performance. If enabled, this will automatically disable simple caching on this entity with a call to cache(false).

entity.compositeCache(true);

entity.compositeCache(false);

var val = entity.cache();
