/** * \file glheader.h * Top-most include file. * * This is the top-most include file of the Mesa sources. * It includes gl.h and all system headers which are needed. * Other Mesa source files should \e not directly include any system * headers. This allows system-dependent hacks/workarounds to be * collected in one place. * * \note Actually, a lot of system-dependent stuff is now in imports.[ch]. * * If you touch this file, everything gets recompiled! * * This file should be included before any other header in the .c files. * * Put compiler/OS/assembly pragmas and macros here to avoid * cluttering other source files. */ /* * Mesa 3-D graphics library * Version: 6.5 * * Copyright (C) 1999-2005 Brian Paul All Rights Reserved. * * Permission is hereby granted, free of charge, to any person obtaining a * copy of this software and associated documentation files (the "Software"), * to deal in the Software without restriction, including without limitation * the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the * Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included * in all copies or substantial portions of the Software. * * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
