   KoViewChild has basically three geometries to keep in sync.
   - The KoDocumentChild geometry (i.e. the embedded object's geometry, unzoomed)
   - Its own geometry (used for hit-test etc.)
   - The KoFrame geometry (the graphical widget for moving the object when active)
 
   So we need to subtract the scrollview's offset for the frame geometry, since it's a widget.
 
   The rules are
   (R1) frameGeometry = viewGeometry(childGeometry) "+" m_frame->{left|right|top|bottom}Border() - scrollview offset,
   (R2) frameGeometry = myGeometry "+" active_frame_border - scrollview offset.
 
   So: (R3, unused) myGeometry = viewGeometry(childGeometry) "+" m_frame->{left|right|top|bottom}Border() "-" active_frame_border
 
   Notes: active_frame_border is m_frame->border() (0 when inactive, 5 when active).
          {left|right|top|bottom}Border are the borders used in kspread (0 when inactive, big when active).
          "+" border means we add a border, so it's a subtraction on x, y and an addition on width, height.
 
          viewGeometry() applies the zoom as well as any other translation the app might want to do
