* This is going to get executed every time they go to open a context menu.
* We want to know *where* they are invoking from, so we do some clever
* hacker in HeaderSup.ColumnHeaderFromContextOpening(...) -- it figures out
* (based on the client rects of the column header items) where they are
* clicking and which column header is appropriate.
*
* NOTE: IF it locates a ColumnHeader and returns it to you, then
* ColumnHeaderFromContextOpeneing CANCELS the context menu operation
* from here from happening and assumes you are going to invoke the context
* menu yourself (which is why we conly call m_ctxmHeader.Show() when
* we get a columnheader back - this allows us to show our ContextMenu
* for our Header columns instead of the context menu for the rest of the
* listview)
*
* ALSO NOTE that we squirrel away the matched columnheader into the first
* menu item in the context menu -- in our case, that's the
* "Remove this column" menu item, so it follows that it needs to know
* what "this" column is. (Other routings may choose to look here for this
* information, so let's make sure to clear the Tag in times when we aren't
* matched...)
