From 3e67e3b1f06488f67d2ebbf844ff40893cc16bf0 Mon Sep 17 00:00:00 2001
From: Jens Arnold <amiconn@rockbox.org>
Date: Fri, 20 Feb 2009 17:13:08 +0000
Subject: Add a rockbox kernel thread for simulator specific tasks, and use
 that for calling the screendump function(s). Fixes screendump in simulators
 for backlight-less targets (Ondio), and reduces mixing of unrelated
 functionality a bit (screendump was called from backlight thread, triggered
 by a sim-only system wide event).
