/**
 * @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.

			 * @brief The DrawStyle enum
			 * How the terminals of a strip are drawn.
			 * The style is chosen for each terminal strip item, when the item is
			 * added to a folio (see TerminalStripItem::setDrawStyle), the layout
			 * only hold the values used by the styles.
			 * Schematic : the classic drawing (header, xrefs, symbols, connections, cables).
			 * RealisticPushIn : the strip seen from above, at scale, like the mounting
			 * drawing of a cabinet : end stops, group marker, push-in wire entries.
			 * RealisticScrew : same as RealisticPushIn, with screw clamps.
			 * The schematic style use most of the values of this class,
			 * the realistic styles use the values prefixed by m_realistic_.
