      7 This file defines the configurations in which bench_pictures should be run
      8 on various platforms. The buildbots read these configurations from the
      9 bench_pictures_cfg dictionary. Everything else in this file exists to help in
     10 constructing that dictionary.
     11 
     12 This code is executed directly on the buildbot so that convenient things like
     13 variables and loops can be used to avoid unnecessary verbosity. With great power
     14 comes great responsibility; don't put any nasty code here. To reiterate, code in
     15 this file will be directly executed on the build slaves.
