/**
* @file lldroptarget.cpp
* @Class LLDropTarget
*
* This handy class is a simple way to drop something on another
* view. It handles drop events, always setting itself to the size of
* its parent.
*
* Altered to support a callback so it can return the item
* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Pulled into its own file for more widespread use
