| * \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 Mesa to be integrated into XFree86 and |
| * 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. |
