+ * such as firing a repeat event), SMIL's endpoint-exclusive timing model
+ * implies that the interval end occurs first. In fact, interval ends can be
+ * thought of as ending an infinitesimally small time before t. Therefore,
+ * A should be sampled before B.
+ *
+ * Furthermore, this distinction between sampling the end of an interval and
+ * a regular sample is used within the timing model (specifically in
+ * SMILTimedElement) to ensure that all intervals ending at time t are sampled
+ * before any new intervals are entered so that we have a fully up-to-date set

+/** Test for SMIL values that are context-sensitive **/
+
+/* See bugs 533291 and 562815.
+
+ The format of each test is basically:
+ 1) create some animated and frozen state
+ 2) test the animated values
+ 3) change the context
+ 4) test that context-sensitive animation values have changed
+
+ Ideally, after changing the context (3), the animated state would instantly
+ update. However, this is not currently the case for many situations.
+
+ For CSS properties we have bug 545282 - In animations involving 'inherit'
+ / 'currentColor', changes to inherited value / 'color' don't show up in
+ animated value immediately
+
+ For SVG lengths we have bug 508206 - Relative units used in
+ animation don't update immediately
+
+ (There are a few of todo_is's in the following tests so that if those bugs
+ are ever resolved we'll know to update this test case accordingly.)
+
+ So in between (3) and (4) we force a sample. This is currently done by
+ calling SVGSVGElement.setCurrentTime with the same current time which has the
+ side effect of forcing a sample.
+
+ What we *are* testing is that we're not too zealous with caching animation
+ values whilst in the frozen state. Normally we'd say, "Hey, we're frozen,
+ let's just use the same animation result as last time" but for some
+ context-sensitive animation values that doesn't work.

+/* Test for Bug 628888 - Animations in external document sometimes don't run
+ *
+ * This bug concerns a condition where an external document is loaded after the
+ * page show event is dispatched, leaving the external document paused.
+ *
+ * To reproduce the bug we attach an external document with animation after the
+ * page show event has fired.
+ *
+ * However, it is difficult to test if the animation is playing or not since we
+ * don't receive events from animations running in an external document.
+ *
+ * Our approach is to simply render the result to a canvas (which requires
+ * elevated privileges and that is why we are using a MochiTest rather
+ * than a reftest) and poll one of the pixels to see if it changes colour.
+ *
+ * This should mean the test succeeds quickly but fails slowly.
