/// \def SFML_DEFINE_DISCRETE_GPU_PREFERENCE
///
/// \brief A macro to encourage usage of the discrete GPU
///
/// In order to inform the Nvidia/AMD driver that an SFML
/// application could benefit from using the more powerful
/// discrete GPU, special symbols have to be publicly
/// exported from the final executable.
///
/// SFML defines a helper macro to easily do this.
///
/// Place SFML_DEFINE_DISCRETE_GPU_PREFERENCE in the
/// global scope of a source file that will be linked into
/// the final executable. Typically it is best to place it
/// where the main function is also defined.
