Bump dri2proto dependency to 2.7.
Bump DRI2INFOREC_VERSION to 7.
This new protocol request effectively allows clients to perform feature
detection on the DDX. The request was added in DRI2 protocol 1.4.
If I had DRI2GetParam in June 2011, when I was implementing support in the
Intel DDX and Mesa for new hardware that required a new DRI2 attachment
format, then I could have avoided a week of pain caused by the necessity
to write a horrid feature detection hack [1] in Mesa. In the future, when
the work begins to add MSAA support to the Intel DDX, having a clean way
to do feature detection will allow us to avoid revisiting and expanding
that hack.
[1] mesa, commit aea2236a, function intel_verify_dri2_has_hiz
v2: If driver doesn't define ds->GetParam, dont' crash. Fall back to
default behavior, per keithp.

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.
