Dragging probably could use several variants, especially since the Shape
Extension is optional, and some (admittedly unsual) X server might not
include it. In some cases, an X server might not be able to drag a window
fast enough to be usable, while a cursor would be OK. 

There are even more advanced techniques (transparent drag) that would need
custom window drawing (at the X level), or a new variant of the Shape
Extension that can deal in alpha levels.

I'd definitely suggest encapsulating the "drag icon" into a new widget
type that can be tought to deal with the needed variants and facilities.
