One of the problems is that the GLX code resets the DRI driver
first and then CloseScreen is called in each driver causing things
to blow up.
Temporarily stop the GLX layer from resetting until an alternative
approach can be worked out.
From a driver perspective, all that needs to be done
is call...
glucoseScreenInit(pScreen);
and glucose will take over for the acceleration. Something
like this should do...
if (!exa && !xaa)
glucoseScreenInit(pScreen);
else if (!exa)
driversXAAinit(...);
else
driversEXAinit(...);
This code has been tested with the i915, i915tex and i810
and there's a few odd rendering quirks that need to be worked
out but they'll probably be in their respective drivers but
the framework is here now.
Additionally, protect libcw setup behind checks for Render, to avoid
segfaulting if Render isn't available (xnest).
The previous setup was an ABI-preserving dance, which is better nuked now.
Now, anything that needs libcw must explicitly initialize it, and
miDisableCompositeWrapper (previously only called by EXA and presumably binary
drivers) is gone.
Yes, two changes in one commit. Sorry 'bout that.
The first change ensures that when pending property values have been
changed, a mode set to the current mode will actually do something, rather
than being identified as a no-op. In addition, the driver no longer needs to
manage the migration of pending to current values, that is handled both
within the xf86 mode setting code (to deal with non-RandR changes) as well
as within the RandR extension itself.
The second change eliminates the two-call Create/AttachScreen stuff that was
done in a failed attempt to create RandR resources before the screen
structures were allocated. Merging these back into the Create function is
cleaner.

I think master and server-1.3-branch are more in sync now.
desiredX and desiredY were not recorded during xf86InitialConfiguration.
desiredX, desiredY and desiredRotation were not recorded during
xf86SetSingleMode.
(cherry picked from commit 36e5227215)
Pending Properties take effect when the driver says they do, so provide an
API to tell DIX when a property effect is made. Also, allow driver
to reject property values in RRChangeOutputProperty.
(cherry picked from commit 8eb288fbd6)
The rotation state is stored in the xf86_config structure which is not
re-initialized at server reset time. Clean it up at CloseScreen time.
