I would like to know what are the following "framebuffer related hints" of GLFW3 function glfwWindowHint :

GLFW_RED_BITS GLFW_GREEN_BITS GLFW_BLUE_BITS GLFW_ALPHA_BITS GLFW_DEPTH_BITS GLFW_STENCIL_BITS

What is the purpose of this?
Usually their default values are enough?
Where are those bits stored? In a buffer in the GPU?
What do they affect? And by that I mean in what way

Thank you in advance!
