Specifics follow below, with a bug-fix list at bottom.
Drawing isolation special effects hook in drawable A new special effects hook has been added to drawable. This can be used with special effects that need to separate the drawing of an individual interactor from its children and other interactors. Each of these methods takes the interactor doing the drawing as a parameter. This boolean indicates whether drawing should continue. At present, there are no subclasses of drawable that take advantage of these hooks, but several are planned.
