// 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.
