[MiNT] gemlib: change some AES constant names

["Arnaud BERCEGEAY" <arnaud.bercegeay@free.fr>]

Hello,

I'd like to change the name of some constants before making them official  
(i mean, before a release of gemlib provides these constants).

For wind_set(WF_WHEEL) modes, at the moment we have:
#define WHL_REALWHEEL   0   /**< AES will send #WM_WHEEL messages */
#define WHL_ARROWWHEEL  1   /**< AES will send #WM_ARROWED messages */
#define WHL_SLDRWHEEL   2   /**< AES will convert mouse wheel events to  
slider events */

I think we don't have to put 'WHEEL' at the end of the name... so i  
propose to change them to the following:
#define WHEEL_MESAG     0   /**< AES will send #WM_WHEEL messages */
#define WHEEL_ARROWED   1   /**< AES will send #WM_ARROWED messages */
#define WHEEL_SLIDER    2   /**< AES will convert mouse wheel events to  
slider events */

(or with WHL_ in place of WHEEL_ as prefix if you prefer)

Any objection ?


best regards,
Arnaud.
