A call to xname sets the background pixmap of the window

Create a window with a background pixel.
Change the background-pixmap using xname.
Verify the background-pixmap was set.

>># ### This should go in XClearWindow etc.
When 
.A background_pixmap
is
.S ParentRelative ,
then each time the background pixmap is required it is taken from the
parent window at the time that it is required,
>>#the background pixmap of the parent window is used
with the background tile origin aligned with the origin of
the parent window.
>># This is not 'the background is set to the background of the parent window'
>>STRATEGY
Set background-pixmap to ParentRelative.
For a variety of parent backgrounds
  Clear child window.
  Verify that background changes to that set for the parent.

Set window-pixmap to None by calling xname.
Map window over a patterned background.
Verify that contents of the window are the same as the parent's.
