Paddle discrepency between body/shape and drawing

[gdurelle]

The Paddle draw is not the representative of its shape, if you move the paddle to the bottom, the ball continue to have collision on it where there is no drawing for what it touches.
In the same way if you move the paddle to make the ball bouncing its bottom part, the ball seems to "cross the paddle".

There is undoubtly a discrepency between the body/shape and the drawing.
Must be due to some bad use of the CP::Vec2 to buld the Shape.
