+/**
+ * Extension interface for {@link dwtx.jface.text.ITextViewer}.
+ * <p>
+ * It provides
+ * <ul>
+ * <li>text presentation invalidation enhancements</li>
+ * <li>text hover management enhancements</li>
+ * <li>a replacement for auto indent strategies</li>
+ * <li>support for custom painters</li>
+ * </ul>
+ *
+ * It extends the means for text presentation invalidation by allowing a
+ * specific region of the presentation to get invalidated. It replaces
+ * {@link dwtx.jface.text.ITextViewer#setTextHover(ITextHover, String)}
+ * with a new method that allows to specify state masks for a better control of
+ * the hover behavior.
+ * <p>
+ * An {@link dwtx.jface.text.IAutoEditStrategy} is a generalization of
+ * the original {@link dwtx.jface.text.IAutoIndentStrategy}. Auto edit
+ * strategies can be arranged in a list that is executed like a pipeline when
+ * the viewer content is changed.
+ * <p>
+ * A {@link dwtx.jface.text.IPainter}is creating and managing visual
+ * decorations on the viewer's text widget. Viewer's can have an open number of
+ * painters. Painters are informed about changes to the viewer content and state
+ * and can take the necessary action in responds to the notification.
