| * Specifically, a real GLX library (like SGI's or the Utah GLX) and Mesa's |
| * pseudo-GLX can be present at the same time. The former being used on |
| * GLX-enabled X servers and the later on non-GLX X servers. |
| * |
| * Red Hat has been using this since Red Hat Linux 7.0 (I think). |
| * This'll be a standard feature in XFree86 4.3. It basically allows one |
