// About OpenGL function loaders: modern OpenGL doesn't have a standard header file and requires individual function pointers to be loaded manually.
// Helper libraries are often used for this purpose! Here we are supporting a few common ones: gl3w, glew, glad.
// You may use another loader/header of your choice (glext, glLoadGen, etc.), or chose to manually implement your own.
// About Desktop OpenGL function loaders:
// Modern desktop OpenGL doesn't have a standard portable header file to load OpenGL function pointers.
