Tweak John's change to handling of rgba arrays

Try to improve the cursor readout and status message.
This could be done better with changes to the backends.
The status (pan/zoom etc) should be indicated via the
state of the buttons, e.g. using radio buttons, rather
than by printing text. The readout should be positioned
to minimize jumping around of the text.

Update CHANGELOG

added a properties method to the artist and inspector to return a dict mapping property name -> value; see sf feature request 2792183
