------- Additional Comments from Dana Jansens <danakj at chromium.org>
Removed the pageScaleFactor from NCCH. It called
deviceOrPageScaleFactorChanged() whenever its viewport is set, as it did
before.

Doing this from WebViewImpl instead doesn't buy us anything really.. we should
do in order:
1. change the deviceScaleFactor() reported from the NCCH
2. report the change to the GraphicsLayer
3. change the size of the GraphicsLayer

1 and 3 happen in NCCH::setViewport, so it's simplest to do 2 there as well.
Else we have to add API to make 1 happen from WebViewImpl separately.
