14 * Draw filled areas as Milky Way and Magellanic clouds.

16 * This class should store SkipLists instead of LineLists. The two methods
17 * are used inside of LineListIndex to access the SkipLists' skip hashes.
18 * This way the same code in LineListIndex does double duty. Only subclassed
19 * by MilkyWay.
