[PATCH] dri2: Copy front to fake front in swapbuffer

[Kristian Høgsberg]

Keith, I've assigned bug 27305 to you as it's now blocking on you.
This process doesn't work.  I don't want to have to spend time
following up everyday and then eventually ping you in irc or email to
get you to apply patches on top of actually fixing the bug.

I really think we need to rethink this process.

Kristian
