Test 'additive' and 'accumulate' attributes.

The four pictures show the effect with the four possible combinations of 'additive' (either 'replace' or 'sum') and 'accumulate' (either 'none' or 'sum'). Because two animations are animating the height, the effects of 'additive' and 'accumulate' are sometimes different than when there is only a single animation.
