Systems responsible for transform propagation

Functions

• mark_dirty_trees
  Optimization for static scenes. Propagates a “dirty bit” up the hierarchy towards ancestors. Transform propagation can ignore entire subtrees of the hierarchy if it encounters an entity without the dirty bit.
• propagate_parent_transforms
  Update GlobalTransform component of entities based on entity hierarchy and Transform component.
• sync_simple_transforms
  Update GlobalTransform component of entities that aren’t in the hierarchy
