This DHTML & Drag&Drop Library adds Drag&Drop functionality
to the following types of html-elements,
provided their names/IDs are passed to SET_DHTML():
- images, even if not positioned via layers,
  nor via stylesheets or any other kind of "hard-coding"
- relatively and absolutely positioned layers (DIV elements).
Moreover, it has extended DHTML abilities,
such as moving, resizing and hiding elements, changing their z-indices,
(all this with layers as well as with images),
swapping images, changing background colors,
writing to layers
or detaching images from their container layers

/* my_PickFunc IS AUTOMATICALLY CALLED WHEN AN ITEM STARTS TO BE DRAGGED.
The following objects/properties are accessible from here:

- dd.e: current mouse event
- dd.e.property: access to a property of the current mouse event.
  Mostly requested properties:
  - dd.e.x: document-related x co-ordinate
  - dd.e.y: document-related y co-ord
  - dd.e.src: target of mouse event (not identical with the drag drop object itself).
  - dd.e.button: currently pressed mouse button. Left button: dd.e.button <= 1

- dd.obj: reference to currently dragged item.
- dd.obj.property: access to any property of that item.
- dd.obj.method(): for example dd.obj.resizeTo() or dd.obj.swapImage() .
  Mostly requested properties:
	- dd.obj.name: image name or layer ID passed to SET_DHTML();
	- dd.obj.x and dd.obj.y: co-ordinates;
	- dd.obj.w and dd.obj.h: size;
	- dd.obj.is_dragged: true while item is dragged;
	- dd.obj.is_resized: true while item is resized, i.e. if <ctrl> or <shift> is pressed
