Interesting animation bug

[Justin Mclean]

Hi,

Here's a curious one:
https://issues.apache.org/jira/browse/FLEX-33974

From what I can see there's a couple of bugs in there.

The most obvious one being:
     public function get playheadTime():Number
     {
-        return _playheadTime + startDelay;
+        return _playheadTime;
     }

And the other fix being updating _playheadTiem not being updated before the 
start time of the animation:

            // Keep starting animations unless our sorted lists return
            // animations that start past the current time
            if (animStartTime < Timeline.currentTime)
                if (anim.playReversed)
                    anim.end();
                else
                    anim.start();
            else
+               anim._playheadTime = intervalTime;
                break;

However with this change we get about 20 effect tests failing, mostly in repeat 
count/repeat delay style tests. It looks to me like the repeat code was 
previously incorrect as duration already included startDelay.

numRepeats += (_playheadTime - duration) / (duration + repeatDelay);

See the original  playheadTime above. Anyone see something I've missed or are 
the current tests  possibly testing current incorrect behaviour?

Thanks,
Justin
