00030  * The pipe object is responsible for maintaining GPU-specific and
00031  * frame-specific data. The identifier passed by the application contains the
00032  * version of the frame data corresponding to the rendered frame. The pipe's
00033  * start frame callback synchronizes the thread-local instance of the frame data
00034  * to this version.
