//	Procedure:
//	    subdIntoPolyMode
//
//	Description:
//	    Given a subdivision surface (with no construction history),
//      create a polygon.  For more details see the description
//      with "subdiIntoPolyMode" function below.
//

global proc subdIntoPolyMode( int $hookAsHistory, int $allowHistory,
							  int $templateSubd )
//
// Description:
//     If $allowHistory is set, we will try and find a polygon in the
//     history of this object, delete that polygon's blind data of
//     the "hierarchical edits" type and put the new blind data on
//     the polygon shape.  If $allowHistory is not set, we will fail
//     if the subd has history in the first place.  If there is no
//     history on the subd, $allowHistory is ignored.  In that case,
//     we will make a new polygon (using "point position" option and
//     the base mesh on the subd -> poly conversion) and give it the blind
//     data that represents the hierarchical edits.  If $hookAsHistory is
//     set, we will then plug everything through polyToSubdiv node into
//     the subd we started with.  Otherwise, we just leave it be.  Note
//     that subd -> poly must be done without history, or we can end up
//     with a loop.
