Function 9 defines the shape, color, and center of the graphics cursor
(the cursor used when the computer is in graphics mode).
This function uses the values found in the screen mask and cursor mask
to build the cursor shape and color.
To pass the screen mask and color masks, assign their values to two
contiguous arrays and pass the address of the first array in ES:DX.
The cursor hot spot values must define one pixel within the cursor.
The values must be within the range -16 to 16.
