Easings / animations for gioui

WIP: looking for input on API / feedback.

This package implements spring based convenience methods for animating layouts or draw operations in Gioui. Please refer to https://godoc.org/github.com/vron/gease for further details.

To see smooth easings on positions, sizes and colors you can run:

go run github.com/vron/gease/example

Inspired by: https://www.react-spring.io/
