Re: Add function to rotate/transpose all windows

Which limitation?  The one that parent windows get resized?  I do use
the normal size of windows (a float between 0 and 1) which does not
change when you make the frame or some ancestor window smaller or
larger.  By design, it should work.  Although when rotating we "flip"
the normal sizes - what was a normal height becomes a normal width and
vice-versa.  Slightly scary ...

For some value of easy.  Can you try to do that?  You would have to
write it from scratch since the rotation code will hardly suit.

Note also that the rotation code

- always rotates the entire frame (you want it to rotate arbitrary
  parent windows only)

- doesn't care about side windows (a similar problem - it should rotate
  the main window instead)

- might fail with atomic windows

- doesn't care about fixed size windows

- might fail with small windows.

The latter two probably mean that we should run the algorithm with fixed
sizes and minimum window sizes in place first.  If 'split-window'
complains, re-run the algorithm ignoring fixed-size windows and minimum
sizes.

And always keep in mind that once our functions exist, people will use
them on-the-fly, expecting them to "just work". They won't forgive the
smallest misbehavior.
