REVISION SUMMARY After going from high zoom to "Auto Fit" a resize event is generated and the resize event handler tries to refresh the page view. Sometimes this can result in an infinite resize loop. Okular fixes this by resizing the content area to the new viewport size. As a consequence both horizontal and vertical scroll range become zero. Now if "Auto Fit" turns out to be "Fit Page" then it is fine but in case of "Fit Width" or "Fit Height", where one scroll range should be non-zero, both scroll bar disappear resulting in a view which appears to be frozen. So to fix this add scroll range to the dimension for which the scroll bar should be visible and then resize. Since the scroll range remains constant, an infinite resize loop won't occur. BUG: 341250 TEST PLAN Zoom in 400% and then select "Auto Fit".
