NAME
       LoadView -- Use a (possibly freshly created) coprocessor instruction
                   list to create the current display.

   SYNOPSIS
       LoadView( View )
                  A1

	void LoadView( struct  View * );

   FUNCTION
	Install a new view to be displayed during the next display
	refresh pass.
       Coprocessor instruction list has been created by
        InitVPort(),  MakeVPort(), and  MrgCop().

   INPUTS
       View - a pointer to the View structure which contains the
       pointer to the constructed coprocessor instructions list, or NULL.

   RESULT
	If the View pointer is non-NULL, the new View is displayed, 
	according to your instructions.  The vertical blank routine 
	will pick this pointer up and direct the copper to start 
	displaying this View.

	If the View pointer is NULL, no View is displayed. 

   NOTE
	Even though a LoadView(NULL) is performed, display DMA will still be 
	active.  Sprites will continue to be displayed after a LoadView(NULL)
	unless an OFF_SPRITE is subsequently performed.
