------- Additional Comments from Vangelis Kokkevis <vangelis at chromium.org>
Thanks for the review! I modified the patch to address the comments.
Specifically:
* Added an enum to the ChromeClient per Ken's and Simon's suggestion and
replaced individual calls by a single call.
* Added a canRender3dTransforms() method to the RenderLayerCompositor.	Media
queries as well as RenderLayer code that needs to know whether 3d transforms
are supported now call this method. I did leave the old
hasAcceleratedCompositing() method intact as it has a different, legitimate,
use.

Please take another look.
