*   idrgdrp.c - Drag and Drop code for dropping vCards in and out of the WAB
*           Several Formats are droppable into other apps:
*           Within the WAB, we drop entryids
*           Within different WABs we drop flat buffers containing full Property
*               arrays (but Named Propery data is lost in the process)(sometimes)
*           We provide data as vCard files that can be dropped into anything asking
*               for CF_HDROP
*           We also create a text buffer and drop that into CF_TEXT requesters
*               The text buffers only hold the same data as the tooltip ..
