So what happens when the page scrolls/zooms now? It's not clear to me why this
is no longer needed

[boliu, 2014/01/25 01:27:39]

Never mind. Found the renderer code to update geometry on commit.

[boliu, 2014/01/25 04:50:13]

Err, scratch that. Renderer commit is only updating geometry, not page scroll
position. Original question stands.

[ycheo (away), 2014/01/28 13:08:53]

I was wrong.
In case of the scroll, this was not needed, but in the zoom, this is needed.

This is a bit of a layering violation here. We shouldn't need to pass |this| up
to the client. ContentViewCores and Clients are 1-to-1.

The details of how to get hold of the ContentViewCore reference in
AwContentViewClient can stay in android_webview code

[ycheo (away), 2014/01/28 13:08:53]

Done.
