- * everything currently running on the GPU has finished before capturing the
- * end snapshot - otherwise the results won't be a complete representation
- * of the work.

- * To achieve this, we stall the pipeline at pixel scoreboard (prevent any
- * additional work to be processed by the pipeline until all pixels of the
