be a DeviceEvent, so put in a check to enforce this.

The macro is sufficient if called during a development cycle, but not
sufficient information when triggered by a user (e.g.
https://bugzilla.redhat.com/show_bug.cgi?id=688693).
Expand what this does to print the event content and a backtrace, so at
least we know where we're coming from. Only the first 32 bytes are printed
since if something goes wrong, the event we have is almost certainly an
xEvent or xError, both restricted to 32 bytes.

Call compMarkWindows() when changing between manual and automatic

compAllowPixmap() is not called when changing between manual and
automatic redirection modes. That means pWin->redirectDraw is left
with an incorrect value, and miComputeClips() gets confused whether
the window is supposed to be treated as transparent or not. Fix
the issue by updating pWin->redirectDraw in compCheckRedirect()
even when not calling compAllocPixmap().

Since extra expose events are no longer generated during window
unredirection, the window contents must be preserved by the server.
So copy the window contents back from the pixmap. The copy can only
be done after the clips have been recomputed, so delay the copy and
the pixmap destruction until ValidateTree is done. Window borders are
restored by HandleExposures and thus don't need to be copied back.

Eliminate the internal MapWindow+UnmapWindow cycle around window
redirection changes. Instead do the work in a single pass by marking
the afected windows and calling ValidateTree and HandleExposures
directly. This gets rid of unnecessary expose events, and invalid
ClipNotify calls during rediredction changes. Now ClipNotify will only
get called with the final clip values, and expose events are only sent
to areas that actually got exposed.

Look for Khronos OpenGL spec files using pkg-config, rather than downloading them
Also add a --with-khronos-spec-dir=PATH configure option so XWin can be directed
where to find these files without using the khronos-spec-files package
XWin with AIGLX requires OpenGL spec files in order to generate wrapper code which:
(1) thunks from the glapi dispatch table which uses the default cdecl calling convention
to native GL functions using the stdcall calling convention.
(2) performs function address lookup for OpenGL 1.2+ functions, which are treated
as extensions and so not directly linkable.

Let configure --enable/disable-aiglx control building of AIGLX for all DDXs. Currently
we can't use --enable/disable-aiglx to control if Xwin DDX is built with AIGLX enabled,
as at the moment it's forced off if we aren't building the X.Org DDX DRI or DRI2 loader
Rearrange things a bit, introducing a new automake conditional, AIGLX_DRI_LOADER to
specifically indicate if the X.Org DDX DRI/DRI2 loader convenience library should be
built, and replace the previous X.Org DDX-specific uses of the AIGLX conditional with that
As before, AIGLX_DRI_LOADER is only enabled if --enable-glx, --enable-aiglx and at least one
of --enable-dri or --enable-dri2 are enabled
This allows the general conditional AIGLX to control if AIGLX is built for the XWin DDX as
well
The C #define AIGLX set by AC_DEFINE(AIGLX) seems to be obsolete, I can't find anything
which checks it
Updated for ajax's "glx: Make --disable-dri not disable AIGLX" patch, which allows DRI2
to be enabled independently of DRI1
