This DHTML & Drag&Drop Library adds Drag&Drop functionality
to the following types of html-elements:
- 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 provides extended DHTML abilities.
