Introduction to xdg-desktop-portal-wlr

The xdg-desktop-portal-wlr package provides the screenshot and screencast portal interfaces for wlroots compositors. Most of the other portal interfaces are provided by xdg-desktop-portal-gtk-1.15.3, but isn't strictly required unless you need those interfaces.
