The Repeater widget is a subclass of the Command widget; see the <!-- xref -->
Command documentation for details. The difference is that the Repeater can call its
registered callbacks repeatedly, at an increasing rate. The default translation
does so for the duration the user holds down pointer button 1 while the pointer
is on the Repeater.

The Repeater widget supports the following actions beyond those of the Command
button:
<variablelist>
<varlistentry>
<term>
<function>start</function>()
</term>
<listitem>
<para>
This invokes the functions on the <function>startCallback</function> and <function>callback</function> lists
and sets a timer to go off in <function>initialDelay</function> milliseconds. The timer
will cause the <function>callback</function> functions to be invoked with increasing
frequency until the <function>stop</function> action occurs.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>
<function>stop</function>()
</term>
<listitem>
<para>
This invokes the functions on the <function>stopCallback</function> list and prevents any
further timers from occuring until the next <function>start</function> action.
