示例1: DrawArrow
// Draw a colored arrow rotated by angle, scaled by scale and at
// the viewport relative position using DebugDraw.
// With no transformation matrix applied, the arrow is drawn in box
// area (3.5f, 3.5f) (see Arrow::k_size) and the overall bounding box
// of the arrow is (-1.75f, -1.75f) to (1.75f, 1.75f).

const float32 scale, const b2Vec2 &position)
