A correction: there seem to be a sound confusion: the official documentation
for Glamor¹ points to old location of the code. One can easily get to
-modesetting driver code by editing the URL as in
"s/glamor/xf86-video-modesetting". I do also know that -modesetting was
included into Xserver, which seems to be okay with those URLs, because they
located in "xorg" part of repository.

Now a plot twist: the documentation is outdated, and the repositories are not
the place of the code nowadays. One can see the activity of
xf86-video-modesetting here

I'm very curious to how to edit this "wiki", it's not the first time I see this
site provides terribly outdated information.
