The worker currently works by receiving GENERATE_BUFFERS messages and will send back the same kind of message, with the generated buffers attached. All properties of the original message are kept, so that when a GENERATE_BUFFERS message comes back to the main thread it is possible to know what and how the buffers where generated. This is typically used for the `projectionTransform` matrix, and will also be necessary when working with tiles.
