set_mode（resolution =（0,0），flags = 0，depth = 0） - > Surface
此功能将创建一个显示Surface。传入的参数是对显示类型的请求。实际创建的显示将是系统支持的最佳匹配。
resolution参数是一对表示宽度和高度的数字。flags参数是其他选项的集合。depth参数表示用于颜色的位数。

        arc里面(100,100,100,100)前面两个表示图形中心的位置，后面两个表示椭圆的a与b
        那么最大为100，只要稍微缩小点，就不圆了，想绘制一个圆，则只需要范围为(0,2*pi)即可，
        后面的数字10表示线宽。
