Hi, firstly thanks to all involved for three.js!

I was wondering if the Canvas (2D context) examples on the project homepage should work on IE9? It's awesome that three.js supports rendering to both WebGL and Canvas and, since IE9 doesn't support WebGL, it would be even more awesome if three.js allowed for cross-browser support.

However when I try the Canvas examples on IE9 I see the FPS counter in the top-left corner and the example title at the top, but otherwise just black screens.

I ask particularly because I see that back in May MS themselves produced a so-called HTML5 "Test Drive" that itself uses three.js:

http://ie.microsoft.com/testdrive/Performance/Galactic/Default.html

This, of course, does work on IE9.

Sorry if I'm missing something obvious here but it'd be great to know if IE9 is supported and why the Galactic demo works but the Canvas examples don't (at least for me).

Cheers,

Mike
