  /**
   * Main constructor for a {@link FigClass}.
   *
   * <p>Parent {@link FigNodeModelElement} will have created the main box {@link #getBigPort()} and
   * its name {@link #getNameFig()} and stereotype (@link #getStereotypeFig()}. This constructor
   * creates a box for the attributes and operations.
   *
   * <p>The properties of all these graphic elements are adjusted appropriately. The main boxes are
   * all filled and have outlines.
   *
   * <p>For reasons I don't understand the stereotype is created in a box with lines. So we have to
   * created a blanking rectangle to overlay the bottom line, and avoid four compartments showing.
   *
   * <p>There is some complex logic to allow for the possibility that stereotypes may not be
   * displayed (unlike operations and attributes this is not a standard thing for UML). Some care is
   * needed to ensure that additional space is not added, each time a stereotyped class is loaded.
   *
   * <p>There is a particular problem when loading diagrams with stereotyped classes. Because we
   * create a FigClass indicating the stereotype is not displayed, we then add extra space for such
   * classes when they are first rendered. This ought to be fixed by correctly saving the class
   * dimensions, but that needs more work. The solution here is to use a simple flag to indicate the
   * FigClass has just been created.
   *
   * <p><em>Warning</em>. Much of the graphics positioning is hard coded. The overall figure is
   * placed at location (10,10). The name compartment (in the parent {@link FigNodeModelElement} is
   * 21 pixels high. The stereotype compartment is created 15 pixels high in the parent, but we
   * change it to 19 pixels, 1 more than ({@link #STEREOHEIGHT} here. The attribute and operations
   * boxes are created at 19 pixels, 2 more than {@link #ROWHEIGHT}.
   *
   * <p>CAUTION: This constructor (with no arguments) is the only one that does
   * enableSizeChecking(false), all others must set it true. This is because this constructor is the
   * only one called when loading a project. In this case, the parsed size must be maintained.
   *
