NAME
    ChangeSprite -- Change the sprite image pointer.

SYNOPSIS
    ChangeSprite( vp, s, newdata)
                 a0  a1   a2

    void ChangeSprite(struct ViewPort *, struct SimpleSprite *, void * )

FUNCTION
    The sprite image is changed to use the data starting at newdata

INPUTS
    vp - pointer to ViewPort structure that this sprite is
              relative to,  or 0 if relative only top of View
    s - pointer to SimpleSprite structure
    newdata - pointer to data structure of the following form.
            struct spriteimage
            {
                UWORD    posctl[2]; /* used by simple sprite machine*/
                UWORD    data[height][2];   /* actual sprite image */
                UWORD    reserved[2];       /* initialized to */
                                                 /*  0x0,0x0 */
            };
    The programmer must initialize reserved[2].  Spriteimage must be
    in CHIP memory. The height subfield of the SimpleSprite structure
    must be set to reflect the height of the new spriteimage BEFORE
    calling ChangeSprite(). The programmer may allocate two sprites to
    handle a single attached sprite.  After GetSprite(), ChangeSprite(),
    the programmer can set the SPRITE_ATTACHED bit in posctl[1] of the
    odd numbered sprite.
    If you need more than 8 sprites, look up VSprites in the
    graphics documentation.
