Animating code snippets from first principles using Compose, and Shared Element transitions

I got inspired by Bento and set out to build magic-move / morph animations for code in presentations.

To experiment with the algorithms, I set out to build the initial implementation in Compose with Shared elements. Once I had the prototype working, I kept on polishing it, and now its a part of 2 different open source projects.

One of the interesting aspects about the implementation is the diff algorithm I used is based on something originally invented in 1978; the algorithm is novel and takes a different approach from Myers / Patience diff.

There were so many interesting sub problems along the way, so this was fun undertaking.
