# Usage: tmux-layout-dwindle [tblrhvsc]...
#
# Arranges panes in the current window into Binary Space Partitions of
# dwindling size towards a corner of the screen (tl, tr, bl, br) along
# a straight line (c) or spiral trajectory (s) while laying out branch
# panes either vertically (v) or horizontally (h) to produce one of 16
# possible orientations, illustrated below, of which "brvc" is default.
#
# Inspired by the dwindle and spiral layout concepts by Niki Yoshiuchi
# in dwm's fibonacci patch <http://dwm.suckless.org/patches/fibonacci>.
