- *

* - Possibly the selected shape's connection points should always

* - It is a little strange to be able to place connection points
* competely outside shapes. Especially when you later can't draw

* same position "on the shape"
- *
+ *
* - I was able to make the connectors attached to a shape fall off
* the shape after scaling it. Not sure the exact cause, but may
* require more investigation/debugging.
- *
+ *
* - The user-defined connection points should be either absolute
* (as the current ones are) or defined as a percentage of the
* shape. These would be based on a toggle setting on the
* toolbar, and they would be placed in exactly the same way by
* the user. The only difference would be that they would be

* obviously the shape transform is applied to them. That way,
* the shape transform is altered. The Percentage version would
* compute their position from the pre-transform dimensions and
* then have the transform applied to them, for example.
- *
+ *
* - The connection points in the test_connection_points.svg file
* seem to follow the shape when it is moved, but connection
* points I add to new shapes, do not follow the shape, either
* when the shape is just moved or transformed. There is
