+  This tests reset behaviour (SMILANIM 3.3.7).
+
+  Reset behaviour is invoked when an element restarts. Some instance times
+  (DOM calls, event-based instance times etc.) should be cleared on a reset.
+  Other instance times should not. This test build up the following timegraph:
+
+    |...|  |...|  |...|  |...|
+    ^      ^      ^      ^
+    A      B      C      D
+
+  Instance times A and C are created by the begin spec and are offset time
+  values which should NOT be cleared on a reset, e.g. begin="1s; 3s"
+
+  Instance times B and D are created by DOM calls and SHOULD be cleared on
+  a reset.
+
+  A reset will occur when the interval beginning with begin instance time
+  B begins. At this time a reset is performed and only instance time D should
+  be cleared. That is, the animation should play THREE (3) times, not four.
+
+  We would like to inspect the result at each of the intervals. To do this
+  using a reftest we duplicate the animate four-times and adjust the timing so
+  that at the animation sample time we are mid-way through each of the four
+  intervals.

+  SMIL3 5.4.3, "Resetting element state" has:
+
+    Any instance times associated with past Event-values, Repeat-values,
+    Accesskey-values or added via DOM method calls are removed from the
+    dependent begin and end instance times lists. In effect, all events and DOM
+    methods calls in the past are cleared. This does not apply to an instance
+    time that defines the begin of the current interval.
+
+  In this test we have the following scenario:
+
+    <set begin="1s" end="2s" dur="1s" ... />
+
+  giving us:
+
+    |...|
+    1   2
+
+  Then at t=1.5s we have the following DOM calls
+
+    anim.beginElementAt(1.5);
+    anim.endElementAt(2);
+
+  potentially giving us:
+
+    |...|  | |
+      ^  
+    1   2  3 3.5
+
+  At t=2s we'll go to look for the next interval and construct one from 3s-3.5s.
+  We should apply restart behaviour at t=3s meaning we'll reset instance times
+  generated by DOM calls in the past however we'll keep the begin instance time
+  at 3s since it defines the beginning of the (now) current interval.  Sticking
+  to the letter of the spec quoted above however, we'll end up clearing the end
+  instance at 3.5s. Yet in this case we should use the active end (t=4s) since
+  there's no end attribute specified.
