const Vec2& center,
float radius,
float angle,---------这个参数有什么用？没看懂，测试了也感觉不出区别。。终于找到了，相对于x轴正方向旋转方向。比如：从90*pi/180度即y轴正方向与圆交点的位置
unsigned int segments,：圆边被切成多少段线段
bool drawLineToCenter：圆心到起始绘制点是否绘制线段
?
?
void drawCircle( const Vec2& center, float radius, float angle, unsigned int segments, bool drawLineToCenter)
{
drawCircle(center, radius, angle, segments, drawLineToCenter, 1.0f, 1.0f);
} ?
