41 * History dialog works like follows:
42 *
43 * There is a history cache hold in the back for primitives of the last refresh.
44 * When the user refreshes, this cache is cleared and all currently selected items
45 * are reloaded.
46 * If the user has selected at least one primitive not in the cache, the list
47 * is not displayed. Elsewhere, the list of all changes of all currently selected
48 * objects are displayed.
