 * @brief System-wide clipboard manager

 * to user actions. It holds a complete SPDocument as the contents. This document
 * is exported using output extensions when other applications request data.
 * Copying to another instance of Inkscape is special-cased, because of the extra
 * data required (i.e. style, size, Live Path Effects parameters, etc.)
