262 	/* find the number of bits needed for the maximum color value */
304  * Reset the color pair, e.g., to whatever color pair 0 is.
324  * Reset color pairs and definitions.  Actually we do both more to accommodate
326  * someone has changed the color definitions.
382 	 * Without ext-colors, we cannot represent more than 256 color pairs.
394 	     * allow for default-color as a component of a color-pair.

486  * Change all cells which use(d) a given color pair to force a repaint.
555  * Extension (1997/1/18) - Allow negative f/b values to set default color
582 	 * Map caller's color number, e.g., -1, 0, 1, .., 7, etc., into
609 	 * Keep track of the number of entries in the color pair table which
