From bb57506d48e783027dbf09ab44c88b40ed7d2fa4 Mon Sep 17 00:00:00 2001
From: Max Horn
Date: Thu, 19 Sep 2002 16:06:51 +0000
Subject: Added overlay to OSystem interface; implemented overlay in SDL
 backend (all other backends, including SDL_gl, still need to implement
 this!); changed NewGUI to make use of the overlay; added Cmd-Q as a shortcut
 for Quit on MacOS X
