[Q] drawing area

What is the purpose of the draw_data entry in gtkdrawingarea?

struct _GtkDrawingArea
  GtkWidget widget;

  gpointer draw_data;

The only place it occurs in the source seems to be in the
initialisation, where it is set to NULL.

static void
gtk_drawing_area_init (GtkDrawingArea *darea)
  darea->draw_data = NULL;

It's not really important for me to know or anything...I'm just a bit
