This union represents four 64-bit integer values or a 64-bit integer rectangle.
Point is considered inside (in is_inside() and is_outside() methods) if its X coordinate is in range [Left, Right) and its Y coordinate is in range [Top, Bottom). It means if point lies directly on Left or Top border it is considered to be inside rectangle but if it lies on Right or Bottom border it is considered to be outside of rectangle.
