Initial set of context-related changes for the JSR-231 API. GLContext
has been exposed in the public API. The GLEventListener callback mechanism has been removed from the core GLContext implementation and moved up to a higher level. GLAutoDrawable now contains the GLEventListener-related methods, and the GLEventListener's methods now receive a GLAutoDrawable as argument. All JOGL demos have been updated for the new APIs. Many FIXMEs and much unimplemented functionality remain. There is slightly different initialization behavior for the demos containing pbuffers, and the deferring of reshape callbacks needs to be rethought. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@320 232f8b59-042b-4e1e-8c03-345bb8c30851
