Description
FilteredList is an unmodifiable ObservableList, that is created by filtering another ObservableList, i.e. it provides the functionality needed by Parent.unmodifiableManagedChildren. FilteredList will have better performance than the current implementation, because it will touch only the elements that have changed in the source list.
Comments
Current FilteredList implementation is too slow for this purpose, need to optimize it and try it again.

The return type should be switched to ObservableList. This would allow some more optimizations in Layouts.

Increasing priority, because unmodifiableManagedChildren will be used by many LayoutPanes.
