    _______________________________________________________

Details:

There is some existing code for units conversion in graphics.cc
(convert_position). However, there is no listener to make use of it when the
"units" properties of various objects are changed.

The objects and units which need to be handled are ...

root
      radio_property units U ,
"inches|centimeters|normalized|points|{pixels}"
figure
      radio_property paperunits , "{inches}|centimeters|normalized|points"
      radio_property units ,
"inches|centimeters|normalized|points|{pixels}|characters"
axes
      radio_property units ,
"{normalized}|inches|centimeters|points|pixels|characters"
text
      radio_property units u ,
"{data}|pixels|normalized|inches|centimeters|points"
