From d78bd439dcb290e4318734693d418937b0bf8129 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Wed, 5 Dec 2012 14:27:41 +0100 Subject: Offscreen testing platform plugin Useful for running auto-tests without popping up a bunch of windows in the windowing system. Thus they can be run in the background and even in parallel without focus issues.
