The macros give warnings when compiled with -pedantic. This commit is
based on a patch by Brian Paul, with minor changes to add do {} while(0)
and rename the check macros.
The optimized Z-test functions assumed that the array of incoming quads
are adjacent, but that's not always true. The fragment shader can cull
intermediate quads, for example.
Now these Z-test functions can cope with non-adjacent quads. A little bit
of performance is probably lost, but it's probably not worth worring about.
This fixes broken glBitmap() Z testing, among other things.

Issue a whole bunch of queries then get the results and render.
Draw the test object in red instead of orange if the result was not
ready when we first queried it.
This reverts commit d6f55492af.
It's both not portable and not safe to trap & exit on ERR. This will
need to use a more invasive approach that tests return code only for
selected, important commands.
Fixes bug 26623. Original patch was submitted by Mathias Frohlich
and modified by Brian.

We probably don't want to propagate this condition to the pipe driver,
this reverts commit f455ca6490 and the
dri_update_buffer flush altogether until an agreement is reached.
Undoes part of commit f455ca6 which would permit pipe->flush() to be
called while the VBO module still had its buffers mapped. Some
drivers care deeply about this. Sorry for not spotting this earlier.
This uses a stamp mechanisms to mark the DRI drawable as invalid.
Instead of immediately updating the buffers we just bump the drawable
stamp and call out to DRI2GetBuffers "later".
"Later" used to be at LOCK_HARDWARE time, and this patch brings back
callouts at the points where we used to call LOCK_HARDWARE. A new function,
intel_prepare_render(), is called where we used to call LOCK_HARDWARE,
and if the buffers are invalid, we call out to DRI2GetBuffers there.
This lets us invalidate buffers only when notified instead of on
every glViewport() call. If the loader calls the DRI invalidate
entrypoint, we disable viewport triggered buffer invalidation.
Additionally, we can clean up the old viewport mechanism a bit,
since we can just invalidate the buffers and not worry about
reentrancy and whatnot.
So far the frontbuffer was only being flushed on st_glFlush and
st_glFinish, however, a co-state tracker may need to make sure that
any frontbuffer changes are already on its way to the actual front.
The dri2 state tracker will need this for event-driven GL applications
to resize properly (It could also be done calling "dri_flush_frontbuffer",
but that way we would flush unnecessarily in the double-buffered case).
Additionally this patch avoids flushing the mesa rendering cache if
PIPE_FLUSH_RENDER_CACHE wasn't specified.
This merges the patches from the series "[PATCH 00/14] More
client-side GLX house cleaning" that were posted to the mesa3d-dev
mailing list. See
http://marc.info/?l=mesa3d-dev&m=126582985214612&w=2
Patches 01 through 04 eliminate a bunch of annoying warnings that I
get when building Mesa.
Patch 05 fixes an inconsistency between the implementation of
glXSwapIntervalMESA and the spec. I chose to favor the code over the
spec in this case. This also eliminated a warning.
Patches 06 through 12 clean up the way that context creation is
performed on the client. When support for GLX_SGIX_fbconfig and the
related GLX 1.3 functions was added, I refactored a bunch
nuts-and-bolts of context creation to CreateContext. The refactor was
a good idea, I just didn't do it right.
Patches 13 and 14 update glxgears_fbconfig to use GLX 1.3 interfaces.
Need to compute two masks here for full and partial 16x16 blocks.
Gives a further good improvement for isosurf particularly:
isosurf 97 -> 108
gears 597 -> 611
This gives a simple access control to the display. It is potentially
slow, but a finer grained mutex can always be used in the future. The
benefit of this simple approach is that drivers need not to worry about
thread-safety.
Use macros to record the status of the function call before returning.
This is the only way that eglGetError can return the status of the most
recent function call.
