 There are a number of environment variables that control the way piglit
 behaves.
 
- PIGLIT_COMPRESSION    
-      Overrides the compression method used. The same values that piglit.conf
-      allows for core:compression.
-
- PIGLIT_PLATFORM
-      Overrides the platform run on. These allow the same values as ``piglit
-      run -p``. This values is honored by the tests themselves, and can be used
-      when running a single test.
-
- PIGLIT_FORCE_GLSLPARSER_DESKTOP
-      Force glslparser tests to be run with the desktop (non-gles) version of
-      glslparsertest. This can be used to test ES<x>_COMPATABILITY extensions
-      for OpenGL
-
- PIGLIT_NO_FAST_SKIP
-       Piglit has a mechanism run in the python layer for skipping tests with
-       unmet OpenGL or window system dependencies without starting a new
-       process (which is expensive). Sometimes this system doesn't work or is
-       undesirable, setting this environment variable to True will disable this
-       system.
-
- PIGLIT_NO_TIMEOUT
-       When this variable is true in python then any timeouts given by tests
-       will be ignored, and they will run until completion or they are killed.
