Thanks for your answer, it works (I'll share my code soon).

Now I have another problem.  This code

(split-window-right (round (* 0.5 (window-width window))))

will split the window into "unequal halves".  I understand the reason,
but is there a simple way to override this behavior?  IOW, how to define
`calculate-columns' so that (split-window-right (calculate-columns col))
makes it so that subsequent (window-width) returns exactly col?
