Further context-related changes for the JSR-231 API. The GLContext

implementations on all platforms have been split into orthogonal
GLDrawable and GLContext concepts. It is now possible to create more
than one GLContet per GLDrawable (though this has not been tested
yet). GLCanvas has been reimplemented in terms of
GLDrawableFactory.getGLDrawable(). More functionality has been moved
from GLDrawable to GLAutoDrawable. Reimplemented lazy sending of
reshape GLEventListener events in GLCanvas and GLJPanel and deleted
notion of deferred reshapes from GLDrawableHelper and elsewhere.
Sharing of textures and display lists is now expressed in terms of
GLContexts instead of GLDrawables. Still need to move pbuffer creation
into GLDrawableFactory from the onscreen GLContext implementations.
Added option to gleem ExaminerViewer to disable automatic redraws upon
mouse events and respecified more of gleem to work on GLAutoDrawables
rather than GLDrawables. Updated all JOGL demos to work with new APIs
and slightly different initialization sequences (in particular, for
pbuffers -- this will change with the addition of
GLDrawableFactory.createGLPbuffer()).
