+    Test of animation sandwich priority based on syncbase dependencies.
+
+    Tests a change to an interval end that leaves the time the same but changes
+    the dependency chain.
+
+    At first c is dependent on b only.
+    Then via script we make b dependent on a's begin time so that c's begin time
+    is indirectly dependent on a's begin time and so should have a higher
+    priority.
