From 492ea455d937041ca98dc95b5a4e11da5e1f91d4 Mon Sep 17 00:00:00 2001
From: Robert Konigsberg <konigsberg@google.com>
Date: Fri, 30 Mar 2012 15:47:10 -0400
Subject: [PATCH] Add sanity test ensuring that creating annotations in a
 drawCallback results in a secondary draw, but initial parameter set to false.

Also minor formatting corrections.
