[hackers] [dwm][PATCH 2/2] add rotatestack()

From: <ssd_AT_mailless.org>
Date: Fri, 21 Oct 2016 01:18:14 +0200

From: ssd <ssd_AT_mailless.org>

rotatestack() allows to rotate the stacked clients in two directions:
either
- pick the last one and put it at the top (zoom it), or
- pick the most recent zoomed one (from the top) and put it to the end.

Effectively, this cycles the zoom through the stacked clients,
preserving the ordering of the stack and the focus.
