	 * 			history based on the minimum character width in the current font
	 * 			at the time the history is turned on. Using a fixed width font is a good
	 * 			idea to minimize memory usage.
	 * @note	If you change the size of the window or you change the font being displayed
	 * 			you should turn off the history and then turn it back on in order to get
	 * 			a new buffer of the correct size for the window/font combination. Strange
	 * 			redrawing and scrolling effects can occur if the buffer is too small to
