Patch to fix the problem in LibreOffice

When using a drawing shape with contour page wrapping, the text is wrapped
around a "virtual object" left or right of the shape after changing zoom level
and entering page preview (or printing / PDF export).

Steps to reproduce: 
1. Add some text to a writer document
2. Draw a rectangle somewhere (right half of page) on the text
3. Switch the rectangle's wrapping to page wrap (this will automatically enable contour wrapping)
4. Zoom out a bit (make sure the entire page width is visible, and the page is centered)
5. Switch to page preview

Expected result:
Text wraps around the rectangle

Actual Result: 
Text wraps around a white space left of the rectangle


This is caused by a missing call to ClrContourCache( pObj ) in
    /sw/source/core/layout/pagechg.cxx:
    void lcl_MoveAllLowerObjs( SwFrm* pFrm, const Point&  rOffset )
in the
    else if ( pAnchoredObj->ISA(SwAnchoredDrawObject) )
case (in the if case, pFlyFrm->NotifyDrawObj() calls ClrContourCache).

The attached patch was created for LibreOffice, but the affected code in OOo looks unchanged.
