Some STR from bug 90584

Steps:
1) Open Draw
2) Draw a shape
3) Turn on glue points (Edit > Glue Points)
4) Insert a glue point onto the shape
5) Right-click the glue point

Had not played much with the diagramming connectors and their anchors/glue
points.

So found this gets a bit awkward.  The Glue Points toolbar and context menu
applies ONLY to "custom" glue points that are added to objects with the Insert
Glue Point action.  The tools have no affect on the "default" glue points
created on the edges of simple polygon draw objects.

In a draw shape absent the "default" glue points the connectors will attach to
the edge of the draw shape with some rules about crossing the body of the
shape. 

The "default" glue points can not be deleted nor their "rules" modified. 

Once a connector has been attached to a "custom" glue point, the glue point can
not be selected to be modified--so the connector has to be pulled away to
another anchor first.

So there should probably be an Uno action--on the context menu, and on the glue
points toolbar--to release the "custom" glue point and send the connector end
to another glue point or sit unconnected on the canvas.  

The unattached "custom" glue point can then be selected. Once selected its
properties can be modified--via the context menu, or on the glue points
toolbar. Or it can be deleted, but just with a <Delete> key.  Seems that with
such a complex object behavior being controlled from both context menu and
toolbar--omission of Delete action from the context menu is incomplete. 

But in the context of expanding Draw diagramming capability, I also could
envision other UI controls that would be of use--duplicate the glue point (with
its directional attribute) for example. But guess with too much more
complexity, the context menu starts to become unclear--using split buttons on
the toolbar might then become the better UI.  

So how often do we expect LO to be used over DIA or Visio--is this a facet to
enhance?
