//
// `EBITENGINE_GRAPHICS_LIBRARY` environment variable specifies the graphics library.
// If the specified graphics library is not available, RunGame returns an error.
// This environment variable can also be set programmatically through os.Setenv before RunGame is called.
// This environment variable works when RunGame is called or RunGameWithOptions is called with GraphicsLibraryAuto.
// This can take one of the following value:
//
// "auto": Ebitengine chooses the graphics library automatically. This is the default value.
