* The `draw_an_object()` function draws a 2D, gold-colored
* triangle:
*
* |[<!-- language="C" -->
* static void
* draw_an_object (void)
* {
* // set the color
* glColor3f (1.0f, 0.85f, 0.35f);
*
* // draw our triangle
* glBegin (GL_TRIANGLES);
* {
* glVertex3f ( 0.0f, 0.6f, 0.0f);
* glVertex3f (-0.2f, -0.3f, 0.0f);
* glVertex3f ( 0.2f, -0.3f, 0.0f);
* }
* glEnd ();

* This is an extremely simple example; in a real-world application you
* would probably replace the immediate mode drawing with persistent
* geometry primitives, like a Vertex Buffer Object, and only redraw what
* changed in your scene.
* If you need to initialize OpenGL state, e.g. buffer objects or
* shadres, you should use the #GtkWidget::realize signal; you
* can use the #GtkWidget::unrealize signal to clean up.
*
* If you need to change the options for creating the #GdkGLContext
* you should use the #GtkGLArea::create-context signal.
