Can you remind me what it actually does? I see several posts on your
blog describing various features, but didn't see a big picture/introduction
for those who haven't been closely following DRI3000 development.
The first Present post tries to explain what the extension does:

Thanks - I guess I hadn't gone far enough back.
In short, it's a way of getting new window content onto the screen in a
vblank-synchronized fashion from a pixmap. This should allow regular X
applications to produce efficient and non-tearing updates, and when
combined with DRI3, will also allow direct rendering applications the
same features.
So, the fundamental purpose of the extension is to get bits from a
pixmap and stuff them on the screen. I called it 'Present', intending to
use the verb form and not the noun (as in I present you with this lovely
pixmap, please put it in my window). Some verb indicating the submission
of new contents is what I'm looking for here.
I don't have any good suggestions. The best alternatives I'm thinking of are
"publish" and "expose", but those both also brings in additional meanings to
confuse people.
