I might be wrong, so don't take my words for granted,
but I really believe you will be much better if you
just forget about "draw" signals at all. You don't
need "draw" for nothing. Just forget that it exists.
Do yourself a favor and erase "draw" from your app, completely,
your app will be simpler and will behave better.

"expose_event" "configure_event" and "motion_notify_event"
are the signals you usually need when handling complex
drawing areas (or opengl_areas for that matter).
