Vertical mouse scrolling does not work without horizontal scrollbar

[JellyRollMorton]

In version 0.8.17, scrolling vertically via the mouse wheel does not work when the horizontal scrollbar is not visible. Example below:

It looks like the code may be inadvertently checking for the existence of a horizontal scroll bar to enable vertical scrolling, and a vertical scrollbar to enable horizontal scrolling. I was able to resolve the problem by swapping that.instance.wtScroll.wtScrollbarV.visible and that.instance.wtScroll.wtScrollbarH.visible in the code below:

      if (deltaY) {
        //ceil is needed because jquery-mousewheel reports fractional mousewheel deltas on touchpad scroll
        //see http://stackoverflow.com/questions/5527601/normalizing-mousewheel-speed-across-browsers
        if (that.instance.wtScroll.wtScrollbarV.visible) { // if we see scrollbar
          that.instance.scrollVertical(-Math.ceil(deltaY)).draw();
        }
      }
      else if (deltaX) {
        if (that.instance.wtScroll.wtScrollbarH.visible) { // if we see scrollbar
          that.instance.scrollHorizontal(Math.ceil(deltaX)).draw();
        }
      }

Yes, it is still on the last version.
