통통한 화살표 그리기

통통한 화살표 그리기

화살표 몸통 조절은 현재 8분의 2 굵기

8분의 4 굵기로 할거면 0.375 -> 0.25, 0.625 -> 0.75

버그있음

resize 시 잘못 표시되는 경우 발생

 - 삼각형 헤드 크기를 조절하는 로직에서 발생하는걸로 생각됨

 - 조절로직: [머리 폭의 절반만큼을 머리 길이로 사용하면서, 머리 폭의 절반이 화살표 길이의 절반보다 큰 경우 화살표 길이의 절반으로 머리 길이를 정한다]

resize 시 화살표 방향 전환

 - onResize override해서 마우스 놓는 위치에 따라 방향 다시 설정하도록?
