    I've been following along and adapting some of the examples from Project Tiny. In the FlyingYolk example there is a ScrollSystem with the following line

    @ut.requiredComponents(ut.Core2D.TransformLocalPosition, game.Scroller)


    I had thought that this decorator would stop the system from running unless those components were present in the scene but it seems like the update (outside of the foreach) is still called.
    1. What does this decorator actually do and is it something that is required?
    2. Is this any different then providing the filter inside the world.forEach?
