 * may be shrunk or ellipsized to fit in the specified width.
 *
 * The <code>positionInStrip</code> argument is the index in the suggestion strip. The indices
 * increase towards the right for LTR scripts and the left for RTL scripts, starting with 0.
 * The position of the most important suggestion is in {@link #mCenterPositionInStrip}. This
 * usually doesn't match the index in <code>suggedtedWords</code> -- see
 * {@link #getPositionInSuggestionStrip(int,SuggestedWords)}.
 *
 * @param positionInStrip the position in the suggestion strip.
 * @param width the maximum width for layout in pixels.
 * @return the {@link TextView} containing the suggested word appropriately formatted.
