callbacks to any child components derived from DragAndDropTarget which the mouse
moves over.

By default, a drop can only be received by DragAndDropTargets inside this container. To
allow targets in the application's other windows to receive it too, pass true for
startDragging()'s allowDraggingToOtherJuceWindows parameter. The drag image then becomes a
desktop window of its own, and targets are found by hit-testing the desktop, so a drag can
be dropped onto a target in any window belonging to the same application.

Note: If all that you need to do is to respond to files being drag-and-dropped from
the operating system onto your component, you don't need any of these classes: you can do this
simply by overriding FileDragAndDropTarget::filesDropped().
