New Revision: 27449

URL: http://svn.gna.org/viewcvs/relax?rev=27449&view=rev
Log:
Created a special Destroy() method for the spin viewer window.

This is for greater control of the spin viewer window destruction.  First the 
methods registered
with the observer objects are unregistered, then the children of the spin 
viewer window are
destroyed, and finally the main spin viewer window is destroyed.  This change 
saves a lot of GUI
resources in the GUI tests (there is a large reduction in 'User Objects' and 
'GDI Objects' used on
MS Windows systems, hence an equivalent resource reduction on other operating 
systems).
