Load ix w/ the sprite offset and bc with the coordinates.  The sprite
should actually be two 8x8 sprites: the first 8 bytes will be put to
video mem and the second 8 bytes will be put to _plotSScreen.  bc is
preserved and ix will be incremented by 16 (now points to the first byte
after the sprite).
