Pull-sync: copies the plain display properties of the whole createjs tree to
the Pixi mirror. Runs once at the end of each tick, after _tick() has
resolved the createjs state.
Invisible nodes are NOT skipped: switching to invisible is itself a state
that must reach Pixi.
No dirty tracking: the Pixi setters either are plain fields (renderable,
visible, alpha) or contain their own equality checks (position, scale,
skew, rotation, pivot), so unconditional copies never invalidate anything.
