Using height should achieve the same effect as width to detect orientation
changes, but is also useful at the initialization, to run code when the layout

Also note: we now look at the dimensions of the above-the-fold, NTPLayout, not
NTPView.

Not sure if using the width of the NTPView had another purpose. +dfalcantara@
