This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
As a first step towards adopting the Compound design system and the new Element Call designs, this pulls in Compound's color tokens and applies them to all existing components. I've tried to choose tokens based on the semantics of where they're used, but in some cases, where the new and old design systems differ in semantics, it was necessary to choose tokens based on their resulting color. These hacks can be removed as we implement more of the new designs.
There were a set of environment variables that we used for custom themes, but Compound has way too many design tokens for that approach to still be a good idea, so I decided to replace them all with a single environment variable that just lets you write arbitrary custom CSS.
by fixing the cause rather than the symptom: this upgrades the code to use the new, recommended JSX transform mode of React 17+, which no longer requires you to import React manually just to write JSX.
This is an Element project (in the vector-im repo) so the Copyright

foundation for some files (and some files were missing headers).
Hopefully explained in comment: we have a heisenbug where we sometimes
lack audio from a certain participant, so this simplifies the audio
path by removing the workaround required to do AEC with spatial audio
on chrome.
Just use isSelected directly rather than makking the button have its
own state. Also, the isPressed from useToggleButton looks like its
whether the user has the mouse button down on it or not rather than
whether the toggle switch is on, which was making the state wrong.
