Eric, that sounds wonderful, but if I understand correctly that's the plan going
forward, right? It won't apply to the existing install base?
The problem is that shipping a Cairo-based Gecko sometime in 2007 requires a
solution that works with existing X installs....
If I'm misunderstanding and there are plans to backport EXA to what are
currently stable releases of distros, that's great!
Is there any way to detect from inside Cairo whether EXA or XAA is used and fall
back on something other than Render as needed?
