[HOpenGL] ANNOUNCE: GLUT 2.2.1.0

[Sven Panne]

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

 * The package is now autoconf-free. API entries are resolved dynamically at 
runtime, just like the OpenGLRaw and GLURaw packages.

 * Support for sRGB framebuffers has been added, just use SRGBMode with 
initialDisplayMode. To use this functionality, you need the upcoming freeglut 
2.6.0 library, older versions and "classic" GLUT do not support this feature.

 * Support for context profiles has been added via initialContextProfile. 
Again, this works with the upcoming freeglut 2.6.0 library only.

Cheers,
