[HOpenGL] ANNOUNCE: GLUT 2.2.2.0

[Sven Panne]

A new version of the GLUT package has been uploaded to Hackage.

   * Fixed linking issues on Mac OS X, the package should work out of the box 
without any warnings or additional flags now.

   * Handle additional mouse buttons via 'AdditionalButton Int' in the 
MouseButton type.

   * Made a few minor typing adjustments, which don't really matter for the 
type synonyms used for the basic OpenGL types so far, but which do matter for 
the upcoming datatype renamings for them.

   * Aesthetic improvements in the brick shader example.

Cheers,
   S.
