CompoundEase
Join multiple eases together into a single compound ease. Imagine an Ease as a graph which goes from (0,0) to (1,1), a linear Ease would be a straight line, and a EaseInOut Ease would be a slanted S shape. A CompoundEase is a set of these graphs all joined together. Each section is an ease which goes from 0 to 1, but the CompoundEase, can change the destination for all but the last Ease. For example, if we joined two LinearEases together, where the first destination was 0.5, then it would be identical to a single LinearEase. However, if we made the first destination 0.1, then the first part of the animation would change slowly (as the gradient is shallow), and the second half would be quick (going from 0.1 to 1 in the same time as the first half took to go from 0 to 0.1).
