very-slow calc loading:

        + SdrPageView::ImpMakePageViewWinRec

So the SdrPageView is responsible for adding
   hundreds of invisible controls 4x over to the sheet.
	+ svx/source/svdraw/svdpagv.cxx
		(ImpInsertControl)
    ** Should try-to re-design to construct control views on demand **

Much of the ListBox construction pain:
     + comes from the early construction of the child / popup window.
	+ window creation / title setting etc. etc.
	+ ImplListBoxFloatingWin (etc.)

    ** should delay floating window (& as much as possible) to idle **
    ** should filter pixmap rendering against the visible screen on OutputDevice
       [ have proto-patch ] **

UnoListBoxControl: toolkit/source/controls/unocontrols.cxx

Hacking:
    + ImpMakePageViewWinRec()
	+ we need get (/ref?) all SdrObjects & whack them on a not-yet-visible list
	+ we need to listen (via XWindowListener?)
	  from 'SdrPageView' for view-pane movement
		+ and update / use InsertControl & on-the-fly
		  instantiate widgets.
	+ 

    
    2 things to catch:
      + view movement ...
      + object movement ...



ListBox:
    + can we re-parent the mpImplLB & delay mpFloatWin creation.
    + bin in-line 'IsDropDownBox' [ protected ]
    +
