-/**
- * A BoringLayout is a very simple Layout implementation for text that
- * fits on a single line and is all left-to-right characters.
- * You will probably never want to make one of these yourself;
- * if you do, be sure to call {@link #isBoring} first to make sure
- * the text meets the criteria.
- * <p>This class is used by widgets to control text layout. You should not need
- * to use this class directly unless you are implementing your own widget
- * or custom display object, in which case
- * you are encouraged to use a Layout instead of calling
- * {@link android.graphics.Canvas#drawText(java.lang.CharSequence, int, int, float, float, android.graphics.Paint)
- *  Canvas.drawText()} directly.</p>
