移動到以某區域為中心的畫面
===
* method 1
padding 沒有效果，改用第二種方法

    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latlng: points) {
        builder.include(latlng);
    }
    LatLngBounds BANGLADESH = builder.build();
    
    int padding = 15; // offset from edges of the map in pixels
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(BANGLADESH, padding);

    // 畫面移動至以圍籬為中心
    mMap.moveCamera(cameraUpdate);
    

* method 2

/**
 *  找一多邊形的涵蓋區域, ex: 以下為一五邊形, 找到最北邊點與最東邊點的交界, 反之亦然
 *
 *                ● — — — — ┼ (north, east)
 *       ●                  │
 *       │             ●    │
 *       │                  ●
 *       ┼ — — ●
 *     (south, west)
