title: Cross browser "jump to"/"scroll" textarea
body: <p>I have a textarea with many lines of input, and a JavaScript event fires that necessitates I scroll the textarea to line 345.</p>
  
  <p><code>scrollTop</code> sort of does what I want, except as far as I can tell it's pixel level, and I want something that operates on a line level. What also complicates things is that, afaik once again, it's not possible to make textareas not line-wrap.</p>
