commit b2939df4a6d25778c7b8b8943c5b2afc902527b8
Author: Leszek Koltunski <leszek@distoretedandroid.org>
Date:   Wed Mar 8 15:36:02 2017 +0000

    Now there's a single place one can have a look at all the Meshes being rendered to a OutputSurface: OutputSurface.renderChildren().
    This will need to get modified for per-object post-processing.
