Probably the easiest way to do it is in BlenderSession::render, so that you get:

for each render layer:
    b_rlay_name = ..
    for each view:
        b_view_name = ...
        ...()

And then in BlenderSession::do_write_update_render_tile use the
b_view_name to write to the right passes.

It would be good to push the view stuff further into Session itself,
especially if we're going to support multiview rendering in the 3D
viewport, but for now I'd start with doing it this way.
