I want my window to always maintain a certain ratio of let's say 1.33333333. So, if the window is width = 800, height = 600 and the user changes the width to 600, I want to change the height to 450 automatically.

I'm already intercepting WM_SIZE but I don't know if it's enough; also I don't know how to change the width or height to maintain my ratio.
