I don't think this is the 100% correct answer as I get log spam saying
(EE) DoSwapInterval: cx = 0x98b8998, GLX screen = 0x96dd780
(EE) AIGLX: cx->pGlxScreen->swapInterval == NULL
but thats better than X exiting in my book.
I'm not sure this the complete proper solution, perhaps it should explicitly fill
in ever field.
This at least makes glxinfo on glcore return sensible information, it doesn't make
gears work yet though.
Get rid of glcontextmodes.[ch] from build, rename __GlcontextModes to
__GLXcontext. Drop all #includes of glcontextmodes.h and glcore.h.
Drop the DRI context modes extension.
Add protocol code to DRI2 module and load DRI2 extension by default.
XIDs for GLX visuals and FBConfigs used to be interchangable and the list of
GLX visuals was identical to the list for FBConfigs. This patch splits handling
of these two data types and allows the X server to pick and choose the FBConfigs
that are exposed as visuals.
When available, use the 2D driver texOffsetStart hook and the 3D driver
setTexOffset hook to save the overhead of passing the pixmap data to
glTex(Sub)Image.
The basic idea is to update the driver specific 'offset' for bound pixmaps
before dispatching a GLX render request and to flush immediately afterwards
if there are any pixmaps bound. This should ensure that the 3D driver can
use pixmaps for texturing directly regardless of the X server moving them
around.
