[HOpenGL] ANNOUNCE: GLUT 2.5.1.0

[Sven Panne]

A new version of the GLUT package is available on Hackage, with the
following new features:

   * Added support for left/right SHIFT/CTRL/ALT special keys.
   * Added skipStaleMotionEvents state flag, making it possible to
skip all but the last motion event.
   * Added leaveFullScreen call.
   * Added support for position, application life cycle and
multi-touch window callbacks.
   * Various object drawing improvements:
        * Added teacup and teaspoon objects, so we support the full
Newell tea set now.
        * Added geometryVisualizeNormals state flag.
        * Added support for drawing objects via VBOs:
vertexAttribCoord3, vertexAttribNormal, and vertexAttribTexCoord2.
        * Added support for menu fonts via new constructor MenuWithFont.

Apart from glutInitErrorFunc and glutInitWarningFunc, which are not
extremely useful IMHO, all freeglut features are now exposed on the
Haskell side.

Cheers,
   S.
