// FUNCTION NAME: InitializeCamera()
//
// RETURNS: If the function terminates before entering the message loop,
// return FALSE.
// Otherwise, return the WPARAM value sent by the WM_QUIT
// message.
//
// LAST MODIFIED: PMcK 11/11/98
//
// DESCRIPTION: calls initialization function, processes message loop
//
// Windows recognizes this function by name as the initial
// entry point for the program. This function calls the
// application initialization routine, if no other instance of
// the program is running, and always calls the instance
// initialization routine. It then executes a message
// retrieval and dispatch loop that is the top-level control
// structure for the remainder of execution. The loop is
// terminated when a WM_QUIT message is received, at which
// time this function exits the application instance by
// returning the value passed by PostQuitMessage().
//
// If the function must abort before entering the message loop,
// it returns the conventional value NULL.
//
//
// ARGUMENTS: hInstance - The handle to the instance of this application
// that is currently being executed.
//
// hPrevInstance - The handle to the instance of this
// application that was last executed. If this is the only
// instance of this application executing, hPrevInstance is
// NULL. In Win32 applications, this parameter is always NULL.
//
// lpCmdLine - A pointer to a null terminated string specifying
// the command line of the application.
//
// nCmdShow - Specifies how the main window is to be diplayed.
