<p>Note that since GIMP 2.4, <em class="parameter"><code>value_callback</code></em>
can be called with
negative values. This is triggered by calls to <a class="link" href="libgimp-gimpprogress.html#gimp-progress-pulse" title="gimp_progress_pulse ()"><code class="function">gimp_progress_pulse()</code></a>.
The callback should then implement a progress indicating business,
e.g. by calling <a href="../gtk2/GtkProgressBar.html#gtk-progress-bar-pulse"><code class="function">gtk_progress_bar_pulse()</code></a>.</p>
