<p>
Easing is acceleration, a change in speed. Easings control how an animation progresses over time.<br/>
An <b>ease-in</b> starts slow and then speeds up.<br/>
An <b>ease-out</b> starts fast and then slows to a stop.<br/>
An <b>ease-in-out</b> combines the two so that the first half is an ease-in and the second half is an ease-out.
