Round the paddle angle

[Natim]

With the current condition, the contact is made between the center of the ball and a point of the pad.

However, sometime, the center doesn't hit the pad but the ball does.
Especially in the angle.

We could:

• Change the condition to handle this case
• Round the pad so that this case doesn't happens anymore.

I was thinking about dealing with this in the 4th blog post: in the original pong

• the ball is a square, so the hitbox is simpler to check
• the paddle bounces the ball with an angle: the closer to the edge the ball gets, the bigger the angle (see The Ball <-> Racket Collision Angle)

This is now fixed in 869c359

Thanks @Natim !
