-This change introduces an abstract ImageData class, and two subclasses. -PlatformImageData allows access to the platform-specific canvas and handles. -SimpleImageData is platform independent, suitable for use in the NaCl proxy. -Also changes ImageData creation messages to use PP_ImageDataDesc instead of serializing to std::string. -Remove NaCl-isms in naming.
