Fixed Issue 173: Adjust gamma, brightness and contrast

Added com.sun.opengl.util.Gamma supporting adjusting of gamma,
brightness, and contrast. API and implementation derived from code in
the LWJGL project. Added demos.gamma.TestGamma demo illustrating how
to use the APIs. Tested on Linux, Mac OS X and Windows. No Solaris
support at this time, although future Solaris releases, being based on
the Xorg server, will probably have support for the required
XF86VidMode extension.
