I'm ok with the TextureMapper changes, please have one of the Cairo folks review the other stuff :)

LGTM, just a small comment.

I don't think the leakRef here is correct because it would returning an Image not an PassRefPtr<Image>, probably removing would be the right option.

BitmapImage::create is returning a PassRefPtr already so the leakRef is unnecessary here. I've fixed it and pushed. Thanks for the review!
