We need an illustration for the beta features page. Who creates these?
I.e. the images shown at https://www.mediawiki.org/wiki/Beta_Features#Current_features_gallery (and used directly within the Special:Preferences page)
An SVG template is available at https://www.mediawiki.org/wiki/File:BetaFeature_Image_template.svg
