Does this need a LayoutStateDisabler?

[fs, 2014/05/02 15:36:09]

Maybe... Can't be used in it's current form though (requires/takes RenderBox).
Maybe that implies we need to overload this for RenderSVGRoot too?

[dsinclair, 2014/05/02 15:40:26]

I don't think it has to take a RenderBox. It just uses the param to get the
view() which is on RenderObject. Locally I just changed the param to be
RenderObject, was going to see what leviw and jchaffraix though about that.

[fs, 2014/05/02 15:53:52]

Yeah, I wasn't sure if that would be frowned upon or not... I suspect it needs
to be sprinkled in one/a few other place though (RenderSVGBlock.)

Ditto, layout state disabler?
