My experiments demonstrate that DID preparation does indeed happen.
Specifically, it is called when miMoveWindow and miSlideAndSizeWindow
call the DDX HandleExposures routine, and it also happens when
miSlideAndSizeWindow calls the DDX ValidateTree routine. It also
happens during PaintWindowBackground and PaintWindowBorder, which get
called even when the window is called with manual composite redirection.

Well, it's getting called in my case.
