 *   속성 판 = 지도 위 떠 있는 판(공용 `createFloatPanel` · 머리 끌어 옮김 · 오른쪽 위) · 고름 있을 때만 —
 *     머리 「구간 N · 선 M · L m」 · ✕ = 풂 · 넓이 [구간][선][같은 해] · 연도(모두 같으면 그 해 · 다르면 「여러 해」 →
 *     고르면 고른 구간 모두 그 해 = 되돌리기 한 걸음) · 고른 구간 줄(누름 = 그 구간만) ·
 *     [방향 바꾸기] [선 지움](선 하나일 때) · [마크 지움](마크 고름) · 보기만 계정 = 값만.
 *   좌측 목록 = 보기 + 고르기만(해 고침은 속성 판 한 곳) — 해 줄(같은 해) · 선 머리 줄(선) · 구간 줄(구간).
