+    Test of animation sandwich priority based on syncbase dependencies.

+    This case includes a complex cycle that should nevertheless produce
+    consistent results.
+
+    If this fails, it will fail intermittently. The test is not so much
+    concerned with which colour should win (there are other tests for that) but
+    simply with determinancy.
