The getter is there only because we have a general rule
that setters have getters. (No write-only properties
when we can avoid them.)

The extents of the layout can differ from the width
in multiple ways:

 - The extents can (and usually are) less than the
   width if there are no lines that long.
 - If there is no break within the set width, the
   layout extents may be wider than the set width.
