C-x {3 o 2 2}

Here is how the transformation would be

 ___________      ___________ 
|           |    |           |
|     A     |    |     C     |
|___________| -> |___________|
|     |     |    |     |     |
|  B  |  C  |    |  B  |  A  |
|_____|_____|    |_____|_____|

IMO this could be useful in the case you have many windows, but are only
really working on 2.  Maybe a good name would be flip-windows-cyclicial?

Since we already have 'window--transpose-1' that already does the fun
stuff, we might as well use it to maximise functionality
