 `TerrainShape` is a new physics shape that lets you add heightfields to physics simulations. Terrain
 can be provided as an `Image`, or as a Lua function for procedural terrain.

+LÖVR's Slack is now deprecated because Slack held our messages hostage!  We migrated all the chat
 history over to a [Matrix](https://matrix.org) homeserver hosted on `#community:lovr.org` and
 bridged everything to a new Discord server.  Keeping the source of truth for chat on a self-hosted,
 open source platform ensures the community is hopefully a bit more resilient to future corporate
 monkey business.

 For the remaining masochists among us who choose to build LÖVR from source, there has been a change
 to the branching system.  The `dev` branch is now the default branch, and `master` has been renamed
