So you are saying as long as the drawing_area_widget is on the screen,
it will emit the map_event? 

So say if I want to display animation with the drawing_area_widget, I
don't need to set the gtk_idle function to the rendering function.
Instead I just create the rendering function as the callback function
for the map_event, since map_event is constantly being emitted by the
widget as long as it's visible. Correct?
