Changes from version 0.2 to 0.3:
================================

- A start has been made to add persistence to the classes in vpApp. The
  code for this is in the ObjectIO module and is modelled after the object
  I/O mechanism in ET++.

- I was inspired by Tkinter to add _setitem__, __getitem__, and GetAttrKeys
  methods to the Graphic class to make it possible to set and access
  attributes using the dictionary syntax. The attributes may be datums
  (active attributes), xresources or others. This should make it easier to
  make an object inspector utility.

- Made the implementation of Mixin classes more robust and at the same time
  easier to use. The change does not affect clients of mixin classes.

- Added some code to the Frame class to make sure that the label will
  always be displayed over the border-frame.

- Added a CheckList class in the TextControls module and made the 
  ClasBrowser use this class.

- Added GetGraphicParent() method to the View class. This method should be
  used when creating the graphic of a View class. 

- Various small changes to the Model and View classes.

- The menu classes now also accept Separator objects (from the MiscGraphic 
  module) as items.  

- Drag-n-drop is turned off when Motif 1.2 is used to allow vpApp objects
  to be dragged. (this requires an updated Xm module)


Changes from version 0.1 to 0.2:
================================

Fixed a number of bugs and made sure that all test programs run without
problems (on an SGI Indigo that is).
