hints.rs

//! This file contains functions to set and get configuration hints, as well as
//! listing each of them alphabetically.
//!
//! 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.
