// =============== How to use ================
// The following function calls should be made directly after OpenGL
// initialization.

// Enable the debugging layer of OpenGL
//
// GL_DEBUG_OUTPUT - Faster version but not useful for breakpoints
// GL_DEBUG_OUTPUT_SYNCHRONUS - Callback is in sync with errors, so a breakpoint
// can be placed on the callback in order to get a stacktrace for the GL error. (enable together with GL_DEBUG_OUTPUT !)

// glEnable(GL_DEBUG_OUTPUT);
// glEnable(GL_DEBUG_OUTPUT_SYNCHRONOUS);

// Set the function that will be triggered by the callback, the second parameter
// is the data parameter of the callback, it can be useful for different
// contexts but isn't necessary for our simple use case.
// glDebugMessageCallback(GLDebugMessageCallback, nullptr);

// REQUIREMENTS: OpenGL version with the KHR_debug extension available.
// modified for C++ by Plasmoxy [7. 5. 2020], I'm using: GLEW and GLFW3, OpenGL 4.6
