/**
 * A widget resembling a diminutive dialog box, designed to be embedded in the
 * #PidginBuddyList.  Mini-dialogs have titles, optional descriptions, and a row
 * of buttons at the bottom; above the buttons is a <tt>GtkHBox</tt> into which
 * you can pack any random widgets you want to add to the dialog.  When any of
 * the dialog's buttons is clicked, the dialog will be destroyed.
 *
 * Dialogs have the following GObject properties:
 * <dl>
 *   <dt><tt>"title"</tt> (<tt>char *</tt>)</dt>
 *   <dd>A string to be displayed as the dialog's title.</dd>
 *   <dt><tt>"description"</tt> (<tt>char *</tt>)</dt>
 *   <dd>A string to be displayed as the dialog's description.  If this is @c
 *       NULL, the description widget will be hidden.
 *   </dd>
 *   <dt><tt>"icon-name"</tt> (<tt>char *</tt>)</dt>
 *   <dd>The Gtk stock id of an icon for the dialog, or @c NULL for no icon.
 *       @see pidginstock.h
 *   </dd>
 *   <dt><tt>"custom-icon"</tt> (<tt>GdkPixbuf *</tt>)</dt>
 *   <dd>The custom icon to use instead of a stock one (overrides the "icon-name" property).</dd>
