	A cset C can be constructed by implementing a TransactionRecorder interface for layers (layer managers?). The recorder will observe all mutations performed on a tree and package them into an IPC message. (This interface could also be used for debugging, to dump layer modifications to stdout.)

			Video decoding fits into this model: decoders will be a slave S that's a thread in a content process, and the decoders publish updates directly to a master M that's the compositor process. The content and browser main threads will publish special "placeholder" video layers that reference "real" layers in the compositor process.
