EA_OnPreDropFromTree

When a user drags any kind of element from the Project Browser onto a diagram, EA_OnPreDropFromTree notifies the Add-In that a new item is about to be dropped onto a diagram. The notification is provided immediately before the element is dropped, so that the Add-In can override the default action that would be taken for this drag.
