// About OpenGL function loaders:
// Modern OpenGL requires individual functions to be loaded manually. Helper libraries are often used for this purpose.
// Here we are using gl3w.h, which requires a call to gl3wInit().
// You may use another any other loader/header of your choice, such as glew, glext, glad, glLoadGen, etc.
// About OpenGL function loaders:
// 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 GLSL version:
// The 'glsl_version' initialization parameter should be NULL (default) or a "#version XXX" string.
