Design and use Cheese emblem
Many GNOME apps or libraries have an emblem, consisting of a symbolic icon on a background, that is used for their GitLab page and Matrix room which helps with their branding. It would be nice if Cheese also uses this emblem style on both platforms. See Initiatives#36 for more info.
Below are some examples of how an emblem could look like. When in use, they will be circular or have rounded corners.
