 * for layout and all the measurements and layouts are done in the onMeasure and onLayout methods.

 * to the left of the photo, the text lines are aligned to the left and the presence icon (if
 * present) is set to the left of the status line.
 *
 * <p>The layout also supports a header (used as a header of a group of contacts) that is above the
 * contact's data and a divider between contact view.
