oh, mmh, this routing_id() is the routing id of the RenderWidget (i.e. the index
of the RW in the RenderThread to route messages from the browser to the
renderer), not the routing id of the context (i.e. the index of the context in
the GpuChannel, to route messages from the renderer to the GPU process).
