43 if set to 1, error checking is disabled as per ``KHR_no_error``. This

83 The ``GL_EXTENSIONS`` string returned by Mesa is sorted by extension
84 year. If this variable is set to year X, only extensions defined on
85 or before year X will be reported. This is to work-around a bug in
86 some games where the extension string is copied into a fixed-size
87 buffer without truncating. If the extension string is too long, the
88 buffer overrun can cause the game to crash. This is a work-around for
