+    An object to take care of the logic for dragging components around with the mouse.
+
+    Very easy to use - in your mouseDown() callback, call startDraggingComponent(),
+    then in your mouseDrag() callback, call dragComponent().
+
+    When starting a drag, you can give it a ComponentBoundsConstrainer to use
+    to limit the component's position and keep it on-screen.
+
+    e.g. @code
+    class MyDraggableComp
+    {
+        ComponentDragger myDragger;
+
+        void mouseDown (const MouseEvent& e)
+        {
+            myDragger.startDraggingComponent (this, e);
+        }
+
+        void mouseDrag (const MouseEvent& e)
+        {
+            myDragger.dragComponent (this, e, nullptr);
+        }
+    };
