* 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.
