void MoveSprite(
         struct ViewPort * vp,
         struct SimpleSprite * sprite,
         WORD x,
         WORD y );

Move sprite to a new position on the screen. Coordinates
are specified relatively to given ViewPort, or relatively
to the entire View (physical display) if the ViewPort is NULL.

This function works also with extended sprites, since
struct SimpleSprite is a part of struct ExtSprite.

vp     - a ViewPort for relative sprite positioning or NULL
sprite - a pointer to a sprite descriptor structure
x      - a new X coordinate
y      - a new Y coordinate

None.

ViewPort is also used in order to specify the physical display.
If it's not specified, Amiga(tm) chipset display is assumed.
This is available only on Amiga(tm) architecture.
