[Net Internals Page] Fix Element Shrinkage from Pinch-to-Zoom

Under pinch-to-zoom, there's no extra redraw event. However, the old
WindowView.resetGeometry() code was sensitive to dimensions
(window.innerWidth/innerHeight) that change with pinch-to-zoom. So when
page is pinch-to-zoomed in, refreshing or resizing triggers redraw,
causing inconsistent element sizing.

Our fix is to use dimensions that are insensitive to pinch-to-zoom,
i.e., document.documentElement.clientWidth/clientHeight. Under 100%
pinch-to-zoom, these are identical to the old dimensions except when
scroll bars are present.
