Marketing blurb [1]:
QtWayland is a Qt 5 module that wraps the functionality of Wayland. QtWayland is separated into a client and server side. The client side is the wayland platform plugin, and provides a way to run Qt applications as Wayland clients. The server side is the QtCompositor API, and allows users to write their own Wayland compositors.
This is mostly needed at the moment to make upstream KDE-CI happy, therefore
we don't wire it into the metaport devel/qt5.
It requires a little change to devel/qt5-qmake, as we needed to modify the
installed bsd.conf to know about wayland/egl.
