//* Description: This procedure converts multiple features to graphics when selected in the Table of Contents.
//****** This procedure only converts those features within the screen display visible bounds for better performance.
//****** Subsitiute "null" for "pSpatailFilter" to convert all features to graphics. Line 123.
//****** The procedure will set the active view as Layout View.
//****** If you want to stay in Data View, manually switch back, or remove Line 184.
