Description: 文实验环境为 .NET 1.1，MAPX4.5。
为了让鹰眼图脱离主View单独浮动，决定使用CJLibrary控件来放置鹰眼图，该控件可由网址[2]下载。
鹰眼图上面有一个红色矩形框，表示主图的当前可视范围。要求点击鼠标左键来移动此框时能够引起主图的联动。
主图上有放大、缩小、移动三个工具按钮，要求主图变化的时候，能够引起鹰眼图矩形框的联动。
实现的易错点在CMapXEagleBar::OnMouseUpInMap函数, 鹰眼图中矩形框的移动要经过如下几步:
a) 得到矩形框四个顶点移动前的屏幕坐标,
b) 计算出中心点坐标,
c) 通过消息传入的参数得到移动后的中心点屏幕坐标
d) 计算前后中心点的偏移(以屏幕坐标作为参考)
e) 计算移动后的矩形框的四个顶点的屏幕坐标
f) 将四个顶点的屏幕坐标转换成地理坐标
g) 显示新的矩形框
