No, we dropped it since it's API was prone to memory leaks. It was also a fairly complicated
class, and filtering is pretty easy to do at the app level.

you can call getHeaderBounds() to get that header's bounding area. Finally, you can call mapPointToAncestor()
on the TableViewHeader to convert the header bounds to display coordinates for displaying
the context menu (you can call getDisplay() on the header to get the display).
