The Wayland frontend thunks allow exceptions to propagate (into C code)

[Alan Griffiths]

For example,

The generated Surface has:

    static void commit_thunk(struct wl_client*, struct wl_resource* resource)
    {
        auto me = static_cast<Surface*>(wl_resource_get_user_data(resource));
        me->commit();
    }

This calls C++ code that might throw, for example:

WaylandBuffer::WaylandBuffer( ... )

which contains

        if (extensions->wayland->eglQueryWaylandBufferWL(dpy, buffer, EGL_WIDTH, &width) == EGL_FALSE)
        {
            BOOST_THROW_EXCEPTION(mg::egl_error("Failed to query WaylandAllocator buffer width"));
        }
