// Purpose: Panel with 3D border. Border style is defined by an integer
//          array of any length. First value is width of a flat at the
//          edge of the panel. Second value is width of a band, which
//          initially rises towards the center. Third value is width of
//          another flat band at the top of the rise. Fourth value is
//          width of a band, which initially falls towards the center.
//          Fifth and subsequent values simply repeat this pattern of
//          flat, rising, flat, falling. For example;
//			A raised panel with insets - {4, 2, 4}
//          A raised rib around panel  - {4, 2, 1, 2, 4}
//          A thick rib and a thin rib - {4, 2, 2, 2, 2, 1, 0, 1, 4}
//          A raised panel with a rib  - {4, 4, 0, 0, 4, 1, 1, 1, 4}
