RNA:

* Property update functions no longer get context, instead they get only
  Main and Scene. The RNA api was intended to be as context-less as
  possible, since it doesn't really matter who is changing the property,
  everything that uses the property should be updated.
* There's still one exception case that use it now, screen operations
  still depend on context too much. It also revealed a few places using
  context where they shouldn't.
* Ideally Scene shouldn't be passed, but much of Blender still depends on
  it, should be dropped when we try to support multiple scene editing.

Change was planned for a while, but need this now to be able to call
update without a context pointer.
