- The additional parameter to Wimp_Initialise, R3, is a pointer to a
- null-terminated list of messages that the application wants to receive
- through event types 17 and 18. The point of this is to further
- optimise the task swapping that the window manager does, since it now
- knows that there is no point in waking up your application if you
- don't want the message its got.
-
- You do *NOT* have to declare the messages at the time of calling
- Wimp_Initialise. There are two additional SWIs which allow you to add
- and remove message numbers.
