  Add environment overrides for ANGLE features.
  
  Allows the application to override ANGLE behaviour without having to
  modify the code or use the ANGLE extension. Useful for testing with the
  command graph refactor.
  
  Adds a new string utility for parsing lists of strings from environment
  variables.
