> Wouldn't it make more sense to refactor ImageBuffer to be able to return PassOwnPtr<GraphicsContext>, rather than work around it here? Benjamin, what do you think?

I don't really like the idea. It is easier to maintain correctness with the current design:
-The GraphicsContext cannot outlive ImageBuffer.
-Having multiple GraphicsContext or a ref-counted GraphicsContext would lead to awful situations.
