Gandalfn, Guillaume, David:

It looks like the major change AIGLX support requires is a rebind 
whenever damage occurs.  To be strictly compliant with the texture 
from pixmap spec, this is also required.  Perhaps rather than use 
the option name "--accelerated-indirect-rendering" which furthers 
the  confusion that indirect rendering previously meant software 
rendering (This was only the case for one GLX implementation), the 
option should be called something like "--conformant", 
"--compatibility", "--strict-binding" or something similar.

Regardless, I like the idea of giving users a clear option to run 
compiz in a guaranteed-to-work, spec-compliant mode, while leaving 
the default behavior to run in the faster, bind-once mode.  If, in 
the future, developers want to add strict locking as discussed to 
death on the xorg list, this option could potentially toggle that 
behavior as well.

Thanks,
-James Jones
