-    # OK, what is going on here?
-    #
-    # When we want to do something that could cause a resize, we:
-    #     - Call startResize(), which sets the size contraint to fixed and resizing to True.
-    #     - Do the resize/hide/show/whatever.  The DisplayImage has its sizeHint() set to our view size.
-    #     - Call finishResize().  If we are totally done with any enclosed operation, we call adjustSize()
-    #       to force the window to recalculate/relayout.
-    #
-    # When the resize actually happens, we get a resize event, but this seems to be before most things
-    # have settled down.  So we do a singleShot(0) timer to get a callback when everything is done.
