	Keycodes are used to detect keyboard events occuring on display windows \c CImgDisplay.
	The field \c key of the \c CImgDisplay structure is updated at real-time with the corresponding keycode
	of the pressed key (or 0 if no keys have been pressed). The keycodes values are given by the variables
	whose names are of the form <tt>cimg::key*</tt>. Above is the keycode for the 'ESC' key, but
	almost all keycodes are thus defined.
        Using CImg-defined keycodes ensures a better portability of your program for other architectures.
