Both DRI and DRI2 are still used largely. Of course to have an implementation
that would cover a broad range of devices and systems is always nice, so both
are welcome in Xephyr.

When you're introducing a feature like this, it's important to keep in mind
how the code is going to be tied with the rest and, for instance, if we could
select only one of those or in a near future easily remove another entirely.
Weak coupling is the word here.


I'd say to send again your patches to review here in the ml (and please send
them inline using git format-patch).


Thank you,
