Thanks for doing this, Boruch.

I think mouse manipulation would be a plus, but I don't expect anyone will do 
that anytime soon.  That might even call for some work at the C level, I'm 
guessing.

Users can drag Emacs-window borders, for example, but we don't have the kind of 
thing Eli is suggesting for most other Emacs graphic thingies, such as menu-bar 
menu names, tool-bar icons, header-line components, and mode-line components 
(and inline images?).

You can't drag their boundaries to resize them, and you can't drag them 
(accessing them away from the boundaries) across each other to reorder them.

The case for `tabulated-list-mode' column headers is, I imagine, a special case 
of header-line components.

It would be good, indeed, if Someone(TM) were to add the ability to do such 
mouse-dragging things at a fairly general level.  I'm not holding my breath, 
however.
