+/**
+ * Tests {@link SingleLayerInfluenceMask}.
+ * 
+ * The test runs two simultaneous looping actions on seperate layers.
+ * <p>
+ * The test <strong>fails</strong> if the visible dancing action does <em>not</em>
+ * loop seamlessly when using SingleLayerInfluenceMasks. Note that the action is not
+ * expected to loop seamlessly when <em>not</em> using SingleLayerArmatureMasks.
+ * <p>
+ * Press the spacebar to switch between using SingleLayerInfluenceMasks and masks
+ * provided by {@link ArmatureMask}.
