// Debug callbacks get created in three ways:
//   o  Application-defined debug callbacks
//   o  Through settings in a vk_layer_settings.txt file
//   o  By default, if neither an app-defined debug callback nor a vk_layer_settings.txt file is present
//
// At layer initialization time, default logging callbacks are created to output layer error messages.
// If a vk_layer_settings.txt file is present its settings will override any default settings.
//
// If a vk_layer_settings.txt file is present and an application defines a debug callback, both callbacks
// will be active.  If no vk_layer_settings.txt file is present, creating an application-defined debug
// callback will cause the default callbacks to be unregisterd and removed.
