title: How to accurately measure svg text height
body: <p>I need to fairly accurately determine the height of the height of the text in my svg elements, unfortunately everything i try to use bounding box and the height i get from this, it's always returns a height that is too big at bigger fonts.</p>
  <p>Is there a way to get a more accurate measurement of text height one that is more dependent on the text within my elements.</p>
