from getting selected. Use e.preventDefault instead of adding and removing
classes on mousedown and mouseup. This keeps the browser from having to
potentially recacluate style on mousedown and mouseup events.

css to mark text as unselectable instead. I can't prove this is
significantly faster with numbers since the call to setup the time out
costs ~.1ms and the call when the timer fires is ~.05. This happens on almost
every mouse event though. Plus, it seems to remove a flicker of highlighting when
frames are skipped and keeps scrolling via the scrollbar from highlighting.
