From 4135e34dfa61d32625ef20e8e38064b465402f4a Mon Sep 17 00:00:00 2001

Subject: I introduced {H,V}RATIO and inc{h,v,}ratio() functions - the default
 behaves like in dwm-4.3, config.arg.h shows how I prefer the ratio being
 handled (for the future I plan to change const char *arg into ..., and
 renaming Client into Win.)
