Calls the GimpPreview::draw_buffer method. GimpPreview itself
doesn't implement this method so the behaviour is determined by the
derived class implementing this method.</para>

<para>
This function starts or renews a short low-priority timeout. When
the timeout expires, the GimpPreview::invalidated signal is emitted
which will usually cause the <parameter>preview</parameter> to be updated.
</para>
<para>
This function does nothing unless the "Preview" button is checked.
</para>
<para>
During the emission of the signal a busy cursor is set on the
toplevel window containing the <parameter>preview</parameter> and on the preview area
itself.</para>
