Mario Kleiner 55db3c9cfc dri3: Robustly clamp to 1.0 if not all screens support 1.2
Checking for dri3_screen_info_rec.version >= 2 is insufficient,
as some shipping drivers, e.g., intel-ddx, nouveau-ddx, set the
version to DRI3_SCREEN_INFO_VERSION, ie. to whatever version the
installed servers headers define. On server 1.20 that would
be version 2, but the drivers still don't support the v1.2
hooks. Make sure all hooks are defined before reporting v1.2.

Also make clamping of reported version to minimum of client
or server robust against possible future clients with possible
majorVersion >= 2.0.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
