Merged JSR-231 branch on to the main JOGL trunk. The main trunk now
contains the evolving JSR-231 Reference Implementation and the JSR-231 branch is permanently closed. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/../svn-server-sync/jogl-demos/trunk@144 3298f667-5e0e-4b4a-8ed4-a3559d26a5f4
