Subprograms: Overlapping islands
An island always requires a pocket as an additional boundary (here,
LBL 1). A pocket can also reduce several island surfaces. The starting
point of this pocket must be within the first island. The starting points of
the remaining intersecting island contours must lie outside the pocket.
