Initially I wanted this for TreeViewNode, but this could be expanded for all nodes.

I would liik to do a hit test on a point on a node and return an Enum value indicating the specific area e.g.
* Scrollbar
* Caption text
* Caption image
* Item text
* Item image
* Border
* Expand/Collapse button
* Nothing (e.g. blank space between end of text and scrollbar)

Currently TreeViewNode.ItemFromPoint(PointF) will return an item even if point is on the scrollbar.
Nor can I tell in MouseClick event if clicking the expand/collapse button triggered the event.

Cheers,
Tim
