PR #5967 only made planes not lose their selection when they strayed outside the map border. This PR makes it possible to select them when they already are outside the map. It also ensures that the selection decorations are drawn. Rank designations, however, will disappear when a unit leaves the map. Fixes #5651 for real, then.
