FranckRJ ab5462e386 Fixed width of CapsuleShape2D::get_rect + set center to center of shape
The width of the rect was only half of the width of the shape, and
the 0;0 coord was at the top left of the rect.
Now the width properly matches the width of the shape, and the 0;0
coord is at the center of the shape. It should match the behavior
of Godot 3.X.
