      9 On hwqual this test is run as a benchmark with a large confidence intervals.
     10 The test also generates output images and verifies their bit accuracy using
     11 MD5 checksums 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.

     32 On hwqual we do not upload performance numbers to the chrome dashboard. We run
     33 glbench with the "-hasty" option to stay well below the BVT limit of 20
     34 minutes. This option will run each test at 512x512 resolution only, run it
     35 only for a fraction of the loops we normally do, and not cool down the
     36 machine between tests. For this PerfControl is disabled.

     38 This benchmark executes glbench, a graphics benchmark designed to time how long
     39 various graphic intensive activities take, which includes measuring:
     40   - fill rate
     41     - blended
     42     - opaque
     43   -Z reject rate
     44   -triangle rate
     45     - no cull
     46     - half cull (half triangles backface culled)
     47     - full cull (mix of back face and degenerates)
     48   - blend rate
     49   - texture fetch
     50     - nearest
     51     - bilinear
     52     - trilinear
     53   - compute
     54     - vertex shader
     55     - pixel shader
