title: how to center print()'d raphael text in a space
body: <p>i am curious as to the proper way to either figure required rendering space for print()'d text or how to have raphael render text from the center outward, as</p>
  
  <pre><code>var an = Raphael("about-navlink", 69, 22), fonts = [0, an.getFont("arialbold")], about_navlink = an.print(0, 10, "about.", fonts[1], 22).attr({fill: "#000000"});
  </code></pre>
  
  <p>makes text originate from the left. i would like to make the parts of this code dynamic with php or pick a static width within which to center and forego the calculation. i have looked throughout raphael's documentation and i do not find anything in the print() reference that discusses text alignment. any help would be greatly appreciated. thanks!</p>
