This came up in Vlad's presentation at XTech today. My suggestion was to
implement drawDiv() or drawElement(), in addition to drawWindow(). That
way, you could fix the potentially hairy text rendering problem with one
simple API call, which could be made using the backup accessible content
which you had placed inside the <canvas> tag anyway. Everyone wins.
<th id="ds1title">Data Set 1</th>
<th id="ds2title">Data Set 2</th>
foo.drawElement(document.getElementById("ds1title"), 45, 60);
(or something like that; you get the idea).
