 *  XXX: Add parenthesis around all arguments so that these macros can be
 *       called with complex expressions.
 *
 *  XXX: All functions which use the PS_CHECK macros must be scrutinized so
 *  that we ensure that an argument which is expected to be output is
 *  psFree'ed before reurning NULL.
 *
 *  XXX: The macros have a name similar to PS_CHECK_CONDITION() and generally
 *  throw a psError if the CONDITION is true.  However, some throw the error
 *  if the CONDITION is false.  This should be consistant.
 *
 *  XXX: rename all these with form PS_ASSERT_CONDITION().
