54         Page containing the shapes

56         @param xActualPage
57         Actual page that's imported - if xPage is a master
58         page, this argument must refer to the using, i.e the
59         page that embeds this specific masterpage. Otherwise,
60         this argument is probably equal to xPage.
61 
62         @param nOrdNumStart
63         Each shape receives a z order number, in order of
64         import (which relies on the fact that the API returns
65         the shapes in draw order - which it does,
66         currently). Since we might mix several pages on screen
67         (e.g. master page and foreground page), this value can
68         be used as an offset to distinguish those pages.
69 
70         @param bConvertingMasterPage
71         When true, then the master page is imported. Otherwise, this
72         object imports the draw page.
