Subject: local_cmmds.tex: Use bending arrows in \tikzstack
X-Git-Tag: v1.0~189
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ef15fe68ba7a74c7f7e5b2a0ac1a04e78828549f;p=thesis.git

local_cmmds.tex: Use bending arrows in \tikzstack

Instead of stacking arrows of different widths.  The small arrow had
been hard to see with the big arrow behind it.  The bending is much
more elegant.
