commit 12f29f9aafb7f4c458410b86ededb0f324bd5a17
Author: Reiner Herrmann <reiner at reiner-h.de>

    constant-seed-for-docs
    
       Use constant seed for example images. Importing random will seed the prng
       with the current system time, which will produce different example images
       on every build. To make the build reproducible, use a constant seed value.
