  # Internal: Asset URI related parsing utilities. Mixed into Environment.
  #
  # An Asset URI identifies the compiled Asset result. It shares the file:
  # scheme and requires an absolute path.
  #
  # Other query parameters
  #
  # type - String output content type. Otherwise assumed from file extension.
  #        This maybe different than the extension if the asset is transformed
  #        from one content type to another. For an example .coffee -> .js.
  #
  # id - Unique fingerprint of the entire asset and all its metadata. Assets
  #      will only have the same id if they serialize to an identical value.
  #
  # pipeline - String name of pipeline.
