      9 Test should not crash and not overheat (which is monitored by PerfControl).
     10 Test generates output images and verifies their bit accuracy using MD5 checksums
     11 which are stored in
     12 ../../deps/glbench/glbench_reference_images.txt (for known good images)
     13 and in ../../deps/glbench/glbench_knownbad_images.txt (for ignored failures -
     14 this should be very rare though).
     15 
     16 If unknown images are encountered the test fails. To resolve this use an
     17 image diffing tool like Beyond Compare and visually check differences between
     18 the unknown image and older versions in ../../deps/glbench-images/.
     19 Note: it should nearly never be required to remove old versions of good/bad
     20 images from these directories.
