void gtk_gl_area_set_auto_render ( GtkGLArea* area, gboolean auto_render )
Sets whether the
GtkGLArea is in auto render mode.
GtkGLArea::render signal will
be emitted every time the widget draws. This is the default and is
useful if drawing the widget is faster.
FALSE the data from previous rendering is kept
around and will be used for drawing the widget the next time,
unless the window is resized. In order to force a rendering
gtk_gl_area_queue_render() must be called. This mode is
useful when the scene changes seldom, but takes a long time to redraw.
