	/**
	 * Construct a ControlDecoration for decorating the specified control at the
	 * specified position relative to the control. Render the decoration only on
	 * the specified Composite or its children. The decoration will be clipped
	 * if it does not appear within the visible bounds of the composite or its
	 * child composites.
	 * <p>
	 * SWT constants are used to specify the position of the decoration relative
	 * to the control. The position should include style bits describing both
	 * the vertical and horizontal orientation. <code>SWT.LEFT</code> and
	 * <code>SWT.RIGHT</code> describe the horizontal placement of the
	 * decoration relative to the control, and the constants
	 * <code>SWT.TOP</code>, <code>SWT.CENTER</code>, and
	 * <code>SWT.BOTTOM</code> describe the vertical alignment of the
	 * decoration relative to the control. Decorations always appear on either
	 * the left or right side of the control, never above or below it. For
	 * example, a decoration appearing on the left side of the field, at the
	 * top, is specified as SWT.LEFT | SWT.TOP. If no position style bits are
	 * specified, the control decoration will be positioned to the left and
	 * center of the control (<code>SWT.LEFT | SWT.CENTER</code>).
