Map mapping custom preset easing strings to linear easing functions. Keys are one-to-one with PresetLinearEasingKey.

This map is not intended to be used on its own—instead, you should use the provided useEasing function, which can be used to access the entries of this map, use your own <easing-function> strings, and invert easing.
