Also extract the "supportedBrowser" logic into a helper (rule of 3)

We realized that the VM actually uses actual rotation center, so I moved the point where division by 2 happens into the VM

Change how information is sent to the vm to match the usual definitions the VM uses for that information

* Player mode

Add isPlayerOnly property on GUI. Move isFullScreen into mode reducer with isPlayerOnly.

Full screen needs to be a separate prop so that GUI knows what to show when exiting full-screen (either player-only or full editor).

- set `gui-body * {box-sizing: border-box;}` instead of expecting it to be set by the enclosing component/playground, and removed uses of content-box (adjusting sizes as needed) 
- Added `!isPlayerOnly` to the conditions for draggable sprites
- rewrote player example to use player mode.

Add more UI states (e.g. differentiating between no access, permission granted but video not loaded, video loaded). CSS cleanup.

Move runtime/renderer related code back into the vm io device. Refactor ModalVideoManager to use the video provider.

Question, should ‘x’ and ‘y’ be localizable?

Separate video provider and modal video manager. Provide hooks in modal video manager for calling functions during stages in enableVideo.
