+   * <p>Layout a "compound label" consisting of a text string and an icon
+   * which is to be placed near the rendered text. Once the text and icon
+   * are laid out, the text rectangle and icon rectangle parameters are
+   * altered to store the calculated positions.</p>
+   *
+   * <p>The size of the text is calculated from the provided font metrics
+   * object.  This object should be the metrics of the font you intend to
+   * paint the label with.</p>
+   *
+   * <p>The position values control where the text is placed relative to
+   * the icon. The horizontal position value should be one of the constants
+   * <code>LEFT</code>, <code>RIGHT</code> or <code>CENTER</code>. The
+   * vertical position value should be one fo the constants
+   * <code>TOP</code>, <code>BOTTOM</code> or <code>CENTER</code>.</p>
+   *
+   * <p>The text-icon gap value controls the number of pixels between the
+   * icon and the text.</p>
+   *
+   * <p>The alignment values control where the text and icon are placed, as
+   * a combined unit, within the view rectangle. The horizontal alignment
+   * value should be one of the constants <code>LEFT</code>, <code>RIGHT</code> or
+   * <code>CENTER</code>. The vertical alignment valus should be one of the
+   * constants <code>TOP</code>, <code>BOTTOM</code> or
+   * <code>CENTER</code>.</p>
+   *
+   * <p>If the text and icon are equal to or larger than the view
+   * rectangle, the horizontal and vertical alignment values have no
+   * affect.</p>
+   *
+   * <p>Note that this method does <em>not</em> know how to deal with
+   * horizontal alignments or positions given as <code>LEADING</code> or
+   * <code>TRAILING</code> values. Use the other overloaded variant of this
+   * method if you wish to use such values.
