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.
