// Filename : menu.c
// Created : 14th November 1996
// By : P.R.Porter
//
// Summary : This module holds the code for the driver96 menu system.
//
// Version Date By Description
// ------- --------- --- -----------------------------------------------
// 1.0 15-Nov-96 PRP Initial Menu functions.
//
// 1.1 20-Nov-96 PRP Fixed the displaying of the bottom menu.
//
// 1.2 08-Nov-96 PRP Made the speed of the menubar dependent upon
// the number of icons displayed.
//
// 1.3 24-Jan-97 PRP Changed the creation of menu icon sprite
// surfaces depending upon whether the hardware
// can stretch blit or not. Also, made it so
// that the full size icon sprite is not stretch
// blitted.
//
// 1.4 10-Feb-97 PRP Changed the creation of menu icon sprite
// surfaces as the capability bits for the drivers
// have been changed. Also, changed the error
// reporting code (for directDraw) so that it
// works.
//
// 1.5 04-Mar-97 PRP Tried to fix bug where running out of video
// memory creating menubar icon surfaces.
//
// 1.6 16-Apr-97 PRP Got rid of bug where task switching causes
// failure of icon draw.
//
// 1.7 23-Jul-97 PRP Checked error value of stretched blit.
//
// 1.8 13-Aug-97 PRP Added CloseMenuImmediately.
//
// 1.9 13-Aug-97 PRP Fixed spelling of above
//
//
// Functions
// ---------
//
// --------------------------------------------------------------------------
//
// int32 ProcessMenu(void)
//
// This function should be called regularly to process the menuber system.
// The rate at which this function is called will dictate how smooth the menu
// system is. The menu cannot be drawn at a higher rate than the system
// vbl rate.
//
// --------------------------------------------------------------------------
//
// int32 ShowMenu(uint8 menu)
//
// This function brings the menu in to view. The choice of top or bottom menu
// is defined by the parameter menu being either RDMENU_TOP or RDMENU_BOTTOM.
// An error code is returned if the menu is already shown.
//
// --------------------------------------------------------------------------
//
// int32 HideMenu(uint8 menu)
//
// This function hides the menu defined by the parameter menu. If the menu is
// already hidden, an error code is returned.
//
// --------------------------------------------------------------------------
//
// int32 SetMenuIcon(uint8 menu, uint8 pocket, uint8 *icon)
//
// This function sets a menubar icon to that passed in. If icon is NULL, the
// pocket is cleared, otherwise, that icon is placed into pocket. The menu is
// either RDMENU_TOP or RDMENU_BOTTOM. Valid error codes include
// RDERR_INVALIDPOCKET if the pocket number does not exist. Initially, there
// are 15 pockets.
//
// --------------------------------------------------------------------------
//
// uint8 GetMenuStatus(uint8 menu)
//
// This function returns the status of the menu passed in menu. Return values
// are RDMENU_OPENING, RDMENU_CLOSING, RDMENU_HIDDEN and RDMENU_SHOWN.
//
