   // thing affecting document time
   gSvg.pauseAnimations();
   // We define a series of scenarios, sample times, and expected return values
   // from getStartTime.
   //
   // Each scenario is basically a variation on the following arrangement:
   //
   // <svg>
   //   <set ... dur="1s" begin="<A-BEGIN>"/>
   //   <set ... dur="1s" begin="<B-BEGIN>"/>
   // </svg>
   //
   // Each test then consists of the following:
   //    animA: attributes to be applied to a
   //    animB: attributes to be applied to b
   //    times: a series of triples which consist of:
   //             <sample time, a's expected start time, b's expected start time>
   //           * The sample time is the time passed to setCurrentTime and so is
   //             in seconds.
   //           * The expected start times are compared with the return value of
   //             getStartTime. To check for an unresolved start time where
   //             getStartTime would normally throw an exception use
   //             'unresolved'.
   //           * We also allow the special notation to indicate a call to
   //             beginElement
   //             <'beginElementAt', id of animation element, offset>
   //
   // In the diagrams below '^' means the time before the seek and '*' is the
   // seek time.
