From eb75c7db3a7372de68347d0df8d58acebc33a9ad Mon Sep 17 00:00:00 2001 From: caryclark Date: Fri, 18 Mar 2016 06:04:26 -0700 Subject: allow one zero length dash If the constructed stroke that represents a dash has a single dash of length zero, and the end cap is square or round, draw the cap. The old code initialized the initial dash length to zero, making it ambiguous whether the first length is zero or not.
