From 97d0f8f43db98e1c5ae49bd32dfc027e6d3a1349 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Trond=20Kjern=C3=A5sen?= Date: Mon, 18 May 2009 09:59:06 +0200 Subject: Fixed a bug which implicitly closed perspective transformed poly lines. When the end point of a line in a path is clipped, only closed paths should have the closing line.
