I'm glad to hear WebGL is moving forward in the standards process!
I do have a (stupid) newbie question, though... I totally understand the typical use cases for rendering 3D images/artwork within the browser. What I'm curious about, though, is whether WebGL will allow me to, for example, create a rectangular polygon, and include a snippet of InnerHTML to display within it.
A picture's worth a thousand words -- even this crappy, quickly-thrown-together mock-up of Yahoo!'s homepage:
Will WebGL help me style an HTML page like that, or do I have to hold my breath and wait for css3-3d-transforms?
