467 * OpenGL programs should use the 'intersection' of both sets of information which is advertised
468 * in the GLX version/extension list. When a program does this it works for certain for both
469 * direct and indirect rendering.
471 * The problem we are having in this area is that ATI's Linux drivers are broken. For some reason

473 * extension list which causes this extension not to be listed. (Wine requires this extension).

1012 * To summarize the following is most likely the correct behavior:
1013 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1014 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1015 * stereo don't care -> it doesn't matter whether we get stereo or not
1017 * In Wine we will treat no-stereo the same way as don't care because it makes
