Looks good to me Brian.
Just a couple of comments.

Let's try to update this when we find other broken applications...
docs/ is growing a lot of stuff, with disparate target audiences.
Maybe we could establish some sort of directory hierachary there:
docs/apps/index.html
docs/apps/viewperf.html
docs/relnotes/1.2.3.4.5.html
docs/specs/
docs/devel/
So that target readers can more easily find stuff that's most relevant
for them.
Yeah, we could do that, but it would also involve updating a bunch of
links in the documents too. Someday.

+<h2>Topogun</h2>
+
+<p>
+<a href="http://www.topogun.com/";>Topogun</a> for Linux (version 2, at
least)
+creates a GLX visual without requesting a depth buffer.
+This causes bad rendering if the OpenGL driver happens to choose a
visual
+without a depth buffer.

+
+<p>
+Mesa 9.1.2 and later (will) support a DRI configuration option to work
around
+this issue.
+Using the<a href="http://dri.freedesktop.org/wiki/DriConf";>driconf</a>
tool,
+set the "Create all visuals with a depth buffer" option before running
Topogun.
+Then, all GLX visuals will be created with a depth buffer.
+</p>
+
BTW, do users need to manually configure this, or will it be
automatically set based on process name?
Manually. Though the DRI conf tool can be used to set it
per-application, I believe.

We actually ship a default drirc already in
src/mesa/drivers/common/drirc, which we expect will get installed by
distro packages. You might want to add the workaround for Topogun there
so it happens automatically...
