Hm, not necessarily. :( Some stuff is kept in local variables inside the Window
class to avoid partial upstream changes invalidating things, so doing
render-related things like updating GLobjects in different treads can lead to
problems.

I don't think it should matter, as long as everything render-related is done in
one thread (which can be a little painful, sorry :().
