 From the TD on alwaysBuffer:

"You can find out whether a stack is currently being buffered by 
comparing its pixmapID property to its windowID property: if these two 
properties are not the same, the stack is buffered."

 From the imag007 tip at www.sonsothunder.com:

   -- The next two lines force the current card image into the offscreen 
buffer
   set the alwaysBuffer of stack pStackPath to false
   set the alwaysBuffer of stack pStackPath to true

(My function only works on "this stack", so this does not apply.  
Maybe.)

Maybe a good test to add to my function and to the imag007 tip is a 
check on the pixMapID and windowMapID.  If they are the same generate 
an error and don't set the imagePixmapID.

(If a stack is not in memory, I don't know if setting the alwaysBuffer 
does what we want.  I haven't looked at that.)
