@gamestdio/easing

This is a grab-bag of Robert Penner's easing equations, most of the code from glsl-easings. Pull requests for optimizations are welcome.

All easing functions only remap a time value, and all have the same signature.

v = ease(t)

Where t is typically a value between 0 and 1, and it returns a new float that has been eased.
