Carl Hetherington f2058a3f87 Comment and (hopefully) simplify Editor::region_drag_motion_callback, fixing problems with dragging regions
to and from tracks in "stacked" display mode.  As a side-effect, enable dragging of regions between layers,
though I'm not entirely sure where this is useful or desirable just yet; dragging regions between layers
currently works in the GUI but has no effect on the model.
