For <A HREF="../DM/DMDA_STENCIL_STAR.html#DMDA_STENCIL_STAR">DMDA_STENCIL_STAR</A> stencils the inactive corner ghost nodes are also included
in the list of local indices (even though those nodes are not updated
during calls to DMDAXXXToXXX().
<P>
Essentially the same data is returned in the form of a local-to-global mapping
with the routine DMDAGetISLocalToGlobalMapping();
<P>
<H3><FONT COLOR="#CC3333">Fortran Note</FONT></H3>
This routine is used differently from Fortran
