Are you sure? :)
How would this ever render then?

[no sievers, 2012/09/25 10:24:04]

Oh this is to force a draw when you switch tabs, ok.
I think I need to rename this method to Composite().

Can you do OnSurfaceUpdated(base::Closure()) or something to avoid the empty
function definition?

Talked with Daniel, not changing this for now.
