  50         Page containing the shapes
  51
  52         @param xActualPage
  53         Actual page that's imported - if xPage is a master
  54         page, this argument must refer to the using, i.e the
  55         page that embeds this specific masterpage. Otherwise,
  56         this argument is probably equal to xPage.
  57
  58         @param nOrdNumStart
  59         Each shape receives a z order number, in order of
  60         import (which relies on the fact that the API returns
  61         the shapes in draw order - which it does,
  62         currently). Since we might mix several pages on screen
  63         (e.g. master page and foreground page), this value can
  64         be used as an offset to distinguish those pages.
  65
  66         @param bConvertingMasterPage
  67         When true, then the master page is imported. Otherwise, this
  68         object imports the draw page.
