Implement optional support for requestAnimationFrame in o3d-webgl client.js replacing the interval timer

[GoogleCodeExporter]

WebGL browsers have implemented versions of requestAnimationFrame eliminating 
the need for setTimeout or setInterval timers. See 
http://paulirish.com/2011/requestanimationframe-for-smart-animating/ as a 
reference. Initially implementing this as an option and hopefully in the future 
we can use it solely.

Added optional support for requestAnimationFrame. Holding off from turning it 
on permanently due to strange issue with Chrome 11 where camera calls to 
transform translate with undefined arguments. This is the error "Uncaught 
TypeError: Cannot read property '0' of undefined". Inserting a simple line of 
code in that function to test for undefined arguments, essentially a no-op 
eliminates the error.

// Example of using the experimental support for requestAnimationFrame in user 
scripts
clearInterval(o3d.Renderer.render_callback_interval_);
o3d.Renderer.installRequestAnimationFrame();
window.requestAnimationFrame(o3d.Renderer.renderClients);
