 // The spec for HTMLCanvasElement.getContext() defines the context
 // creation attributes as type "any". In order to eliminate custom
 // bindings for getContext(), we define a dictionary that contains the
 // union of all of the context types' attributes. Note that it is not
 // possible to use a union type for this purpose because two dictionary
 // types are not distinguishable.
