This change removes max_width, and renames min_width to preferred_width.

Currently, if max_width is left at its default value (0), any attempt
to set the bubble's width via SetWidth() is blocked, because the width
is clamped to min_width, max_width. Further, there is only one case in
which max_width is initialized to a different value than min_width, so
the decision was made to move the clamping logic from the base class
into that subclass.
