/*
 * TYPEDEF: SRM_SRF_Parameters_Pair
 *
 *    This data type specifies a orward reference to SRM_SRFParamsPair,
 *    defined in the implementation of the SRM API. This allows the
 *    definition of SRM_SRFParamsPair to be hidden, while allowing the
 *    declaration of functions which can use it via SRM_SRF_Parameters_Pair.
 *
 *    This structure is used to optimize multiple coordinate conversion
 *    calls without permitting the user to see the API's internal data
 *    structure.
