Present didn't provide the 'kind' argument to the
present_complete_notify hook that GLX uses to construct
GLX_BufferSwapComplete events, so GLX was reporting events for
PresentCompleteKindMSC notifications, which resulted in duplicate
GLX_BufferSwapComplete events and crashes in clutter.

Mesa no longer supports rendering to anything less. GLX 1.2 requires
that the server advertise at least one GLX visual. GLX 1.3 and 1.4 are
more subtle: they require at least one fbconfig capable of window
rendering, and _also_ require that window-capable fbconfigs have a
non-zero value for the GLX_VISUAL_ID. In either case we should refuse
to init GLX if there's not at least one GL-capable visual on at least
one screen.

The attack surface for indirect GLX is huge, and it's of no use to
most people (if you get an indirect GL context, you're better served
by a immediate X error than actually trying to use an indirect GL
context and finding out that it doesn't support doing anything you
want, slowly). This flag gives you a chance to disable indirect GLX
in environments where you just don't need it.
I put in both the '+' and '-' arguments right now, so that it's easy
to patch the value to change the default policy.

These functions are called from the GL driver, in some series of GL
calls by GLX. If some server component (like glamor CreatePixmap for
GetBuffers()) changes the GL context on us, we need to set it back or
the later GL calls will land in the glamor context instead of the GLX
context.

GLX is trying to track whether the context it wants is current, to
avoid the glFlush() (and the rest of the overhead) that occurs on all
MakeCurrent calls. However, its cache can be incorrect now that
glamor exists. This is a step toward getting glamor to coordinate

The visualSelectGroup wasn't getting set (since our DRI drivers don't
use it), and and since it's the top priority in the sort order, you
got random sorting of your visuals unless malloc really returned you
new memory. This manifested as Xephyr -glamor rendering to a
multisampled window on my system, which as you might guess was
slightly lower performance than expected.

Well, that was lame. The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth. So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.
So until the DRI drivers are fixed we should just continue to lie about
Y inversion. GLX_DONT_CARE is what libGL would make up for that
attribute if we hadn't sent it, so just send that instead.

We now expect to be linked against something that provides the GL API,
instead of manually grubbing about in the DRI driver's dispatch table.
Since the GLX we expose calls GL functions that are meant to be looked
up dynamically, also add a way to thunk through to GetProcAddress.
This includes a refresh of the generated sources, which requires a
correspondingly new Mesa.
The GetProcAddress stubs are at the moment merely enough to make this
link against Mesa 9.2, but should really be provided for everything not
in the OpenGL 1.2 ABI.

Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and
three releases ago. The main reason to have wanted DRI1 AIGLX was to
get a GLX compositor working, but DRI1's (lack of) memory management API
meant that the cost of a GLX compositor was breaking direct GLX apps,
which isn't a great tradeoff.
Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose
some functionality here, since it and only it has support for
NV_texture_rectangle. Since that's required for every extant GLX
compositor I know of, I conclude that anybody with a savage, say, would
probably not notice AIGLX going away, since they wouldn't be running a
GLX compositor in the first place.
In the future we'd like to use GL in the server in a more natural way,
as just another EGL client, including in the GLX implementation itself.
Since there's no EGL implemented for DRI1 drivers, this would already
doom AIGLX on DRI1 (short of entirely forking the GLX implementation,
which I'm not enthusiastic about).

I broke this, back in:
commit a48dadc98a28c969741979b70b7a639f24f4cbbd
Author: Adam Jackson <ajax@redhat.com>
Date: Mon Mar 21 11:59:29 2011 -0400
glx: Reimplement context tags
In that, I changed the glx client state to not explicitly track the list
of current contexts for the client (since that was what we were deriving
tags from). The bug was that I removed the code for same from
glxClientCallback without noticing that it had the side effect of
effectively de-currenting those contexts, so that ContextGone could free
them. So, if you had a client exit with a context still current, the
context's memory would leak. Not a huge deal for direct clients, but
viciously bad for indirect, since the swrast context state at the bottom
of Mesa is like 15M.
Fix this by promoting Bool isCurrent to ClientPtr currentClient, so that
we have a back-pointer to chase when walking the list of contexts when
ClientStateGone happens.
v2: Explicitly call __glXFreeContext on the ClientStateGone path. Our
current context might be one we got from EXT_import_context and whose
creating client has since died. Without the explicit call, the creating
client's FreeClientResources would not free the context because it's
still current, and the using client's FreeClientResources would not free
the context because it's not an XID it created. This matches the logic
from a48dadc.
