public double getShapeToLabelRatio() {
		return 1.0;
	}
Returns the size factor for a shape relative to its label. Shapes are sized based on the
label of a vertex so that the label can fit inside the shape (mostly). Some subclasses
will need to override this value to some value &gt; 1 to fit the label in the shape. For 
example, a rectangle shape does not need to be extended because text naturally fits. But
for a shape like a triangle, its bounding box needs to be bigger so that text doesn't
"stick out" in the narrow part of the triangle.
