It is a translation of wx.gizmos.TreeListCtrl, so it suffers of the
same problems you outlined below.

I can refactor something to force HyperTreeList to use some code from
CustomTreeCtrl (the event handler class, the TreeListItem class for
example), but the drawing/mouse handling code (and others), although
they look similar to the CustomTreeCtrl ones, would be quite
complicated (for me, at least) to merge with the CustomTreeCtrl one.
