Rebased to upstream again, dropped the HACK patch that worked around a
bug in Cairo, and rewrote some patches to better follow the naming
convention. The new branch is:

git://git.collabora.co.uk/git/user/pq/wayland-demos.git screensaver-v4

As for the Cairo issue with decorationless toytoolkit apps that use
EGL, I quote
http://lists.freedesktop.org/archives/wayland-devel/2011-December/001669.html

  The fix in Cairo is commit 909f4a4a7f0a6082f4f1e9edaba8034a819a12ec
  "gl: Set the destination for swap buffers, required by EGL at least".
...
  Unfortunately, at the time of writing this, the Cairo master HEAD is
  still too broken in the GL backend to be used. Therefore I suggest to
  use Cairo 9bdfae6e218185dd9cc2770f5e7d4ca887ce and add the above fix on
  top.

Without that fix in Cairo, wscreensaver does not work in the
screensaver (default) mode.
