Eelco Dolstra 213aefac17 * Look for the current OpenGL driver in /var/state/opengl-driver.

Eelco Dolstra 410f21887a * A quick hack to get accelerated OpenGL working: just use the driver
in /usr/lib/libGL.so.1 (which will typically load a driver in
  /usr/X11R6/lib/modules/dri).  This has been tested on a i915
  graphics card; it should work with most open source X.org drivers.
  For NVidia's proprietary drivers (which we cannot build ourselves
  anyway), some more symlinks are necessary; I'll add those later.

  So to get hardware-accelerated Quake 3, do:

  $ nix-env -p /nix/var/nix/profiles/opengl -i xorg-sys-opengl
  $ nix-env -i quake3-demo
  $ quake3

Eelco Dolstra 7f74c406c4 * In Quake 3, by default use Mesa as the OpenGL implementation. But
allow the OpenGL implementation to be overriden through the
  OPENGL_DRIVER environment variable.  If it is not set, we use the
  implementation installed in the profile
  /nix/var/nix/profiles/opengl, allowing easy late binding by the
  user, e.g.,

    $ nix-env -p /nix/var/nix/profiles/opengl -i nvidia-sys-opengl

  might install the NVidia OpenGL implementation.

  The code that does this is not specific to Quake 3: it has been
  factored out into build-support/opengl/mesa-switch.sh.  Presumably
  any application that requires hardware-accelerated OpenGL needs it.

* Add the Quake 3 demo to the cache.
