+Create a plugin that, when added to a ProseMirror instance,
+causes a decoration to show up at the drop position when something
+is dragged over the editor.
+
+Nodes may add a `disableDropCursor` property to their spec to
+control the showing of a drop cursor inside them. This may be a
+boolean or a function, which will be called with a view and a
+position, and should return a boolean.
