This function defines the minimum and maximum horizontal positions reported. If the cursor is
outside the new boundary, the cursor is moved just inside the boundary. If the minimum
parameter is greater than the maximum parameter, the parameters are swapped.

F33_GRAPH_CURSOR (AX

,.. This function defines the graphics cursor or sprite. This allows the programmer to define what
the 16 pixel by 16 pixel sprite is to look like. The programmer defines both the AND mask and
the XOR mask. The masks must be defined in contiguous memory. You must also pass in the
sprite hot spot. The hot spot must be in the range of -16 to 16. The term"hot spot" refers to
the point, inside or outside of the sprite, which positions the sprite. The hot spot origin is defined
by the upper left hand corner of the sprite.
