From 288d4b6ebed85e0d3bf6d3aecf75f2627b70402d Mon Sep 17 00:00:00 2001
From: Sean D'Epagnier <geckosenator@freedesktop.org>
Date: Sat, 5 Aug 2006 08:24:29 +0000
Subject: Modularized code into multiple files.

Added gamemode stubs, iconify support, joystick stubs.

Fixed color index mode, added 8 bit alpha blending, enabled cmaps even
with 15, 16, 24, and 32 depths as some fbdev drivers need this.

Fixed compiling with -ansi

Using SIGIO for keyboard input, so that vt switching is enabled even
if the program is locked.

Fixed numerous small bugs.
