Fix zoom overview width and postscale for non-wide-viewport mode.

                // we always force, in case our height changed, in which case we

                // still want to send the notification over to webkit.

                // Keep overview mode unchanged when rotating.

                float newScale = mActualScale;

                if (mWebView.getSettings().getUseWideViewPort()) {

                    final float zoomOverviewScale = getZoomOverviewScale();

                final float newScale = (mInZoomOverviewBeforeSizeChange) ?

                    newScale = (mInZoomOverviewBeforeSizeChange) ?

                        zoomOverviewScale : Math.max(mActualScale, zoomOverviewScale);

                }

                setZoomScale(newScale, mUpdateTextWrap, true);

                // update the zoom buttons as the scale can be changed

                updateZoomPicker();

            }

        } else {

            // If not use wide viewport, use view width as the zoom overview width.

            newZoomOverviewWidth = viewWidth;

            newZoomOverviewWidth = Math.round(viewWidth / mDefaultScale);

        }

        if (newZoomOverviewWidth != mZoomOverviewWidth) {

            setZoomOverviewWidth(newZoomOverviewWidth);
