// at static-init time. These macros may eventually be phased out in favor of
// a simpler interface that does not require static init.
// NOTE: Having a macro called Configure proved to be problematic with some
// DX9 headers. To avoid that in the future we provide a new family of macros
// prefixed by DTool and deprecate the old ones, to be removed from the
// codebase sometime in the future.
// This macro should appear in the config_*.h file.
