Schedules an item for removal. This function leaves some stale indexes around in the BSP tree if called from the item's destructor; these will be cleaned up the next time someone triggers purgeRemovedItems().
Note: This function might get called from QGraphicsItem's destructor. item is being destroyed, so we cannot call any pure virtual functions on it (such as boundingRect()). Also, it is unnecessary to update the item's own state in any way.

Remove widget from the popup list. Important notes:
widget is guaranteed to be in the list of popups, but it might not be the last entry; you can hide any item in the pop list before the others, and this must cause all later mouse grabbers to lose the grab.

This is the final dispatch point for any events from the scene to the item. It filters the event first - if the filter returns true, the event is considered to have been eaten by the filter, and is therefore stopped (the default filter returns false). Then/otherwise, if the item is enabled, the event is sent; otherwise it is stopped.

emitFocusChanged needs to be false when focus passes from one item to another through setActivePanel(); i.e. when activation passes from one panel to another, to avoid getting two focusChanged() emissions; one focusChanged(0, lastFocus), then one focusChanged(newFocus, 0). Instead setActivePanel() emits the signal once itself: focusChanged(newFocus, oldFocus).
