This was causing a crash randomly, due to random memory contents.
Use xcalloc to prevent this in the future, due to future changes or mistakes.
Set the drawableType to include GLX_PIXMAP_BIT and GLX_PBUFFER_BIT.
The new libGL supports these.
Set the max Pbuffer width/height, based on the results of a test program.
We may someday want to revisit this depending on what users need, so that
we create a CGLContextObj, make it current, and call glGetIntegerv to
gather the information at runtime.
(cherry picked from commit c7e3383309)
Reorder some header files and provide some types earlier on.
Remove the static __GLXextensionInfo __glDDXExtensionInfo; that isn't
used in 1.4 or 1.5, and seems to have been removed from 1.6. Remove
the data structures associated with that too.
Remove __glXAquaDrawableResize. The GLX structure doesn't use
it anymore, and the Apple version did nothing useful before.
__glXAquaDrawableSwapBuffers(): base no longer contains a drawGlxc
member. Now provide the the Apple/Aqua context in the __GLXAquaDrawable
struct. Add the context member to the __GLXAquaDrawable struct.
Remove the fallback configs. They aren't used in 1.4 or 1.5 either.
Remove init_visuals(). It's not used in 1.4 or 1.5 either.
In the drawable constructor initialize the state properly, including
the new context member.
Remove glAquaResetExtension() -- it's not used anymore.
This has been tested remotely and proven to work with glxgears,
fire, various texture programs I wrote, and various Mesa demos.
(cherry picked from commit d514152195)
Use a __GLXconfig linked list struct to store the configurations for the
fbconfigs and visuals in a pGlxScreen.
Also, remove the __GLXvisualConfig/GlxSetVisualConfigs code that isn't used
anymore. There is more code we can remove later, but I want to do that in
separate commits.
(cherry picked from commit 94162b0f8a)
Add various GLX extensions to the list of supported extensions.
Reformat the oddly formatted code in some areas.
Use xalloc and xfree instead of malloc and free.
(cherry picked from commit 755f53eb40)
Add some commentary about future directions needed for the GLX drawable
creation and destruction code.
Match xalloc with xfree.
I made some minor formatting improvements.

In attach() check for pDraw being NULL, and also print an ErrorF message,
because we eventually want to track down why this is occuring.
It's unclear how this occurs, but as I noted in the 1.4 branch, I believe that
the DrawablePtr/struct _Drawable -> id is the member being accessed that causes
KERN_PROTECTION_FAILURE at 0x0000000000000004
This passes my tests using: env LIBGL_ALWAYS_INDIRECT=1 ./sometest.
I fixed a warning: caused by initializing the screen->base.visuals with the
configs. It is a ** not a *. It seems that some other part of GLX will
initialize this for us.
(cherry picked from commit 17f6a261fc)
GL/capabilities.c: #if 0 (for now) any capabilities above 8 bits per channel,
because they introduce drawing problems.
GL/indirect.c: Comment out some visual setup code that shouldn't be running, and
actually seemed to cause some problems. The current visualConfigs.c code seems
to do a reasonable job of setting up visuals for XQuartz.
GL/visualConfigs.c: Make use of the proper visual .class. Eliminate depth 0.
It seems we really just want 24 for now, and 0 I think was a flaw in the original
code.
(cherry picked from commit 1e5f63f15e)
This gives us a *lot* more visuals, and they should be more accurate.
Some of the visuals may have been wrong before. This may enable more
OpenGL programs to behave correctly.
I also suspect libGL needs a little work to handle some of these correctly.
