561 * OpenGL programs should use the 'intersection' of both sets of information which is advertised

1254 * To summarize the following is most likely the correct behavior:
1255 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1256 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1257 * stereo don't care -> it doesn't matter whether we get stereo or not

1259 * In Wine we will treat no-stereo the same way as don't care because it makes
