[Bug 243677] www/webkit2-gtk3: make WPE renderer optional (disabled by default, as it's unreliable)

--- Comment #4 from Greg V <greg at unrelenting.technology> ---
My patch for fixing the renderer — still waiting for upstream reaction, but
this makes everything work for me. (the eglmesaext is just for building with
mesa-dev, this has already been done upstream, the real part is the zero)
