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