+ *
+ * The convention for naming hints is SDL_HINT_X, where "SDL_X" is the
+ * environment variable that can be used to override the default.
+ *
+ * In general these hints are just that - they may or may not be supported or
+ * applicable on any given platform, but they provide a way for an application
+ * or user to give the library a hint as to how they would like the library to
+ * work.
