setVirtualForeground operates on the user’s original video output. The Zoom Meeting’s dynamic gallery trims the original video. If I want to set some image on the virtualForeground that keeps all important details even when displayed in a dynamic gallery, I need to know which regions of video will always be displayed, regardless of gallery mode.

What are the bounds on aspect ratio for a user’s video in the Zoom Meeting’s dynamic gallery?
