//  Description:
//      This implements the various global proc and variables needed 
//		for polygons
//

// these proc are called mainly from PolygonsMenu.mel and EditPolygonsMenu.
// however, we need to have them defined here, because polygons menu
// is read only once the user has pulled down the polygons menu:
// this could make the shelf and other user defined UI fail
// if the PolygonsMenu has not been created and these functions are called.
