Improvements to Fancy Zones

### Description of the new feature / enhancement

FancyZones act as "Monitors" in Microsoft teams and Zoom. allowing you to share only content within the zone.

### Scenario when this would be used?

This would be useful for ultrawide monitors where you only want to share a area of the screen in a standard 16:9 format for the benefit of the people viewing your screen in the Teams meeting

### Supporting information
