How do I maintain the aspect ratio set on creation when resizing my window in glfw? I tried searching for a guide/tutorial but I couldn’t find any answers as to how… I know it will be something inside a function passed to the `glfw.set_window_size_callback` function but what would that be?

See the Window Size limit section of the documentation:  
[https://www.glfw.org/docs/3.3/window\_guide.html#window\_sizelimits](https://www.glfw.org/docs/3.3/window_guide.html#window_sizelimits)

Specifically [glfwSetWindowAspectRatio](https://www.glfw.org/docs/3.3/group__window.html#ga72ac8cb1ee2e312a878b55153d81b937).
