/**
 * @brief The TerminalStripLayoutPattern class
 * A class with all values used to define how a terminal strip must be drawn.
 * Most of the value are public, some values are private and have getter / setter
 * because when these values change we need to compute the change.
 *
 * The values with name '_y_offset' mean offset is relating to the top
 * of the QGraphicsItem used to display the terminal strip.
 *
 * The terminal strip can display up to 4 terminal level,
 * the value used for multilevel terminal are stored in  several QVector (m_terminal_y_offset, m_terminal_height, m_bridge_point_y_offset).
 * The order of the values are from the most back terminal to the front terminal.
