Fixes missing update when setting opacity on an item that had opacity 0.0
We need to set the paintedViewBoundingRectsNeedRepaint flag when an item
becomes visible again because when the item has opacity 0.0 the
paintedViewBoundingRects struct can get set as outside of viewport, so the
next time the item is set to visible again we need to diregard this cached
data (otherwise the item will not be updated).
