/**
* The ruler widget is placed alongside a document to measure position
* and size of entities within the document, such as margins, paragraph
* indents, and tickmarks.
* The ruler widget sends a SEL_CHANGED when the indentation or margins
* are interactively changed by the user.
* If the document size exceeds the available space, it is possible to
* scroll the document using setPosition().  When the document size is
* less than the available space, the alignment options can be used to
* center, left-adjust, or right-adjust the document.
* Finally, a special option exists to stretch the document to the
* available space, that is to say, the document will always be fitten
* with given left and right edges substracted from the available space.
