Right. I think I read a message from you in the archives where you
detailed this goal. And certainly my intention is not to sully
ChamplainView with lots more junk.

So far I'm in agreement with this.

I do like the idea of having full ClutterActor flexibility (github
knows I've been having lots of fun playing with
ChamplainMarker.set_scale()), one thing that is important to me is
that I be able to specify 'this actor should be aligned to the center
of the ChamplainView', and have it stick there (even if the view is
resized) without having to connect a signal handler to 'notify::width'
and reposition the Actor myself. I just want some part of the
libchamplain code to handle the positioning so I don't have to think
about it.

Thanks Jiří.
