From 749803415e61265facb5b16d919c51d2d12dbd0a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rog=C3=A9rio=20Brito?= Date: Sat, 18 Jul 2015 18:04:13 -0300 Subject: [PATCH] Common/webgl-utils.js: Trivial conversion of DOS to Unix line ends. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This was automated with the `dos2unix` tool and while it may look enourmous, it *only* changes the EOL characters.
