William Jon McCann b08c15d986 Prefer symbolic icons for the default message dialog image 
The icon does not need high resolution or color to indicate the type
of message and the color can detract from the important part of the message.

* SECTION:gtkmessagedialog
* @Short_description: A convenient message window
* @Title: GtkMessageDialog
* @See_also:#GtkDialog
*
* #GtkMessageDialog presents a dialog with an image representing the type of
* message (Error, Question, etc.) alongside some message text. It's simply a
* convenience widget; you could construct the equivalent of #GtkMessageDialog
* from #GtkDialog without too much effort, but #GtkMessageDialog saves typing.
*
* One difference from #GtkDialog is that #GtkMessageDialog sets the
* #GtkWindow:skip-taskbar-hint property to %TRUE, so that the dialog is hidden
* from the taskbar by default.
*
* The easiest way to do a modal message dialog is to use gtk_dialog_run(), though
* you can also pass in the %GTK_DIALOG_MODAL flag, gtk_dialog_run() automatically
* makes the dialog modal and waits for the user to respond to it. gtk_dialog_run()
* returns when any dialog button is clicked.
* <example>
* <title>A modal dialog.</title>
* <programlisting>
* dialog = gtk_message_dialog_new (main_application_window,
* GTK_DIALOG_DESTROY_WITH_PARENT,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error loading file '&percnt;s': &percnt;s",
* filename, g_strerror (errno));
* gtk_dialog_run (GTK_DIALOG (dialog));
* gtk_widget_destroy (dialog);
* </programlisting>
* </example>
* You might do a non-modal #GtkMessageDialog as follows:
* <example>
* <title>A non-modal dialog.</title>
* <programlisting>
* dialog = gtk_message_dialog_new (main_application_window,
* GTK_DIALOG_DESTROY_WITH_PARENT,
* GTK_MESSAGE_ERROR,
* GTK_BUTTONS_CLOSE,
* "Error loading file '&percnt;s': &percnt;s",
* filename, g_strerror (errno));
*
* /&ast; Destroy the dialog when the user responds to it (e.g. clicks a button) &ast;/
* g_signal_connect_swapped (dialog, "response",
* G_CALLBACK (gtk_widget_destroy),
* dialog);
* </programlisting>
* </example>
*
* <refsect2 id="GtkMessageDialog-BUILDER-UI">
* <title>GtkMessageDialog as GtkBuildable</title>
* <para>
* The GtkMessageDialog implementation of the GtkBuildable interface exposes
* the message area as an internal child with the name "message_area".
* </para>
