 * Instances of this class are controls which are capable

    Events:

 * Note: The NO_BACKGROUND, NO_FOCUS, NO_MERGE_PAINTS,
 * and NO_REDRAW_RESIZE styles are intended for use with Canvas.
 * They can be used with Composite if you are drawing your own, but their
 * behavior is undefined if they are used with subclasses of Composite other
 * than Canvas.
 * 
    
 * Note: The CENTER style, although undefined for composites, has the
 * same value as EMBEDDED which is used to embed widgets from other
 * widget toolkits into SWT.  On some operating systems (GTK), this may cause
 * the children of this composite to be obscured.
 * 
    
 * This class may be subclassed by custom control implementors
 * who are building controls that are constructed from aggregates
 * of other controls.
