Subject: Also define a default functor rule for the new Polyline
X-Git-Tag: v0.03~6
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FLaTeX-TikZ.git;a=commitdiff_plain;h=93edf9c5c04a04fbd3c8dbf04eacaf66736ff6ee

Also define a default functor rule for the new Polyline

Otherwise the Chain default rule is used instead, but it does not know how
to create a Polyline.
