Subject: [PATCH] Redraw the window after an expose event

Expose events, according to the X11 documentation, signify when the
contents of a window region have been lost but until now we have been
ignoring this event for unknown reasons.

Handle this event by redrawing the window entirely. While this is not a
perfect solution, the optimal one would be to only redraw the
region that was lost, it's simpler to implement currently and better
than losing the contents of the window entirely.
