Make it a 512 square and specify its purpose as just "maskable" since this can't

Through several avatar work iterations it's no longer used.

...so that the text is more readable in the presenter mode. Chrome by
default uses 'detail' for screen sharing. I went with the 'text' here,

Watch out when updating beyond this version:
https://github.com/react-native-community/react-native-svg/issues/1354

This change serves 2 purposes:

- (Hopefully) make the recent list entry options easier to discover
- Remove the (now unmaintained) swipeout dependency

Change the preferredVideoQuality and maxReceiverVideoQuality values to Ultra HD resolutions. The requested resolution can be as high as 4K to facilitate VPaaS customers to request 4K. The sender video resolution will always max out at the value specified in the video constraints from config.js settings.
