    That all sounds nice but us blockheads were wondering if you could you
    provide an example of setting the plane_mask and the "corresponding
    bit in both the foreground and background pixels..."?

(I don't normally have time to gift wrap things ... :-)
If the plane you want is plane N (numbered from zero), you set the plane mask
to (1L << N), and you set foreground to (1L << N) and background to 0 (or
vice versa, depending on how you want the image to appear).
