title: Full UI widget toolkit rendering in WebGL
body: <p>Is there currently any full widget toolkit providing components rendering in WebGL only? Similar to the <a href="http://www.lw-zone.org/word/" rel="noreferrer">ZebraUI project</a>, which renders a full UI component set in HTML5 canvas?</p>

  <p>The idea is to write pure JavaScript, and still be able to shaders to render the components.</p>
