Fixes a systemic bug where Python tp_getset property setters bypassed the
render cache dirty flag system (#144). The animation/C++ setProperty() path
had correct dirty propagation, but direct Python property assignments
(e.g. frame.x = 50, caption.text = "Hello") did not invalidate the parent
Frame's render cache when clip_children or cache_subtree was enabled.
