Recent WebKitGTK releases have removed functionality required if Emacs
is to display web pages within off-screen windows, so I think our
priority should be restoring the browser to a functional condition,
rather than introducing non-essential extensions that will only serve a
dwindling number of users.  The approach I suggest is to port xwidget.c
to the WPE library:

  https://wpewebkit.org

which is designed for displaying web pages onto off-screen buffers that
are later copied as the client pleases, a perfect match for Emacs's
requirements.
