| <!-- an1: Change width from 0 to 50 to 100, all linear interpolated. As additive is set to sum it should add the current baseValue |
| to the new animated value each time a value from the values list is consumed. Expected: |
| At 0s, width=10, at 2s, width=50+10=60, at 4s, width=100+10=110. |
| |
| Our testing harness will change the baseValue from 10 to 60 at 5s. The current animated value (before the script change) |
| is: <baseValue>+<animValue>: 10 + (100/6*5) = 93.333 at this point. As we change the baseValue to 60, the equation now looks like: |
| 60 + (100/6*5) = 143.333. Before the script change the last second of the animation would have animated width from 85 to 110. |
| Due the script change its now animating from 93.999 to 143.333 during the last second. |
