* The rail button's shape is basically 3 cylinders stacked on top of each other. To achieve this 3D shape in a 2D
* way, the top and bottom faces of the cylinder are drawn as 2D ellipses and the side faces are 2D lines. To be
* able to select the side faces, extra invisible rectangles are added. This is because otherwise, there would just
* be empty space between the 2D lines and thus the rail button could not be selected.
* @param component
* @param transformation
