DragDropManager is a singleton that tracks the element interaction for +all DragDrop items in the window. Generally, you will not call +this class directly, but it does have helper methods that could +be useful in your DragDrop implementations.
+In intersect mode, drag and drop interaction is defined by the +overlap of two or more drag and drop objects.

+In point mode, drag and drop interaction is defined by the +location of the cursor during the drag/drop

+The number of pixels that the mouse needs to move after the +mousedown before the drag is initiated. Default=3;
+The number of pixels that the mouse needs to move after the +mousedown before the drag is initiated. Default=3;
+The number of milliseconds after the mousedown event to initiate the +drag if we don't get a mouseup event. Default=350
+The number of milliseconds after the mousedown event to initiate the +drag if we don't get a mouseup event. Default=350
+Flag to determine if we should prevent the default behavior of the +events we define. By default this is true, but this can be set to +false if you need the default behavior (not recommended)
+Flag to determine if we should stop the propagation of the events +we generate. This is true by default but you may want to set it to +false if the html element contains other features that require the +mouse click.
+Helper function for getting the best match from the list of drag +and drop objects returned by the drag and drop events when we are +in INTERSECT mode. It returns either the first object that the +cursor is over, or the object that has the greatest overlap with +the dragged element.
+The array of drag and drop objects +targeted

+Is drag and drop locked?
+Is drag and drop locked?
+True if drag and drop is locked, false otherwise.
+My goal is to be able to transparently determine if an object is +typeof DragDrop, and the exact subclass of DragDrop. typeof +returns "object", oDD.constructor.toString() always returns +"DragDrop" and not the name of the subclass. So for now it just +evaluates a well-known variable in DragDrop.

+true if typeof oDD = DragDrop
+Refreshes the cache of the top-left and bottom-right points of the
+drag and drop objects in the specified group(s). This is in the
+format that is stored in the drag and drop instance, so typical
+usage is:
+
+Ext.dd.DragDropManager.refreshCache(ddinstance.groups);
+
+Alternatively:
+
+Ext.dd.DragDropManager.refreshCache({group1:true, group2:true});
+
+@TODO this really should be an indexed array. Alternatively this
+method could accept both.
an associative array of groups to refresh
