    /**
     * The TextLayoutFormat class holds all of the text layout properties. These properties affect the format and style of a text flow at the container level, paragraph level, and text level.  Both the ContainerController class and the FlowElement base class have <code>format</code> properties that enable you to assign a TextLayoutFormat instance to them. Assign a TextLayoutFormat object to a container to affect the format of all of the container's content. Assign a TextLayoutFormat object to a FlowElement descendant to specify formatting for that particular element: TextFlow, ParagraphElement, DivElement, SpanElement, InlineGraphicElement, LinkElement, and TCYElement.
     * In addition to the <code>format</code> property, these classes also define each of the individual TextLayoutFormat properties so that you can override the setting of a particular style property for that element, if you wish. <p>Because you can set a given style at multiple levels, it is possible to have conflicts. For example, the color of the text at the TextFlow level could be set to black while a SpanElement object sets it to blue. The general rule is that the setting at the lowest level on the text flow tree takes precedence. So if the ligature level is set for a TextFlow instance and also set for a DivElement, the DivElement setting takes precedence. </p><p>Cascading styles refers to the process of adopting styles from a higher level in the text flow if a style value is undefined at a lower level. When a style is undefined on an element at the point it is about to be rendered, it either takes its default value or the value cascades or descends from the value on a parent element. For example, if the transparency (<code>textAlpha</code> property) of the text is undefined on a SpanElement object, but is set on the TextFlow, the value of the <code>TextFlow.textAlpha</code> property cascades to the SpanElement object and is applied to the text for that span. The result of the cascade, or the sum of the styles that is applied to the element, is stored in the element's <code>computedFormat</code> property.</p><p>In the same way, you can apply user styles using the <code>userStyles</code> property of the ContainerController and FlowElement classes. This  property allows you to read or write a dictionary of user styles and apply its settings to a container or a text flow element. The user styles dictionary is an object that consists of <em>stylename-value</em> pairs. Styles specified by the <code>userStyles</code> property take precedence over all others.</p><p>Most styles that are undefined inherit the value of their immediate parent during a cascade. A small number of styles, however, do not inherit their parent’s value and take on their default values instead.</p><p><strong>Style properties that adopt their default values, if undefined, include:</strong> <code>backgroundAlpha</code>, <code>backgroundColor</code>, <code>columnCount</code>, <code>columnGap</code>, <code>columnWidth</code>, <code>lineBreak</code>, <code>paddingBottom</code>, <code>paddingLeft</code>, <code>paddingRight</code>, <code>paddingTop</code>, <code>verticalAlign</code></p>.
