- TGLSAViewer::SavePicture is now a public method. Therefore it is now

  possible to generate gif files of the GL-Viewer from the command line
  doing:

  root [1] TGLSAViewer *glv = (TGLSAViewer *)gPad->GetViewer3D();
  root [2] glv->SavePicture("gl.gif");

  TGLSAViewer::SavePicture has also been modified to allow to generate
  animated gif files. Example:

  root [1] TGLSAViewer *glv = (TGLSAViewer *)gPad->GetViewer3D();
  root [2] glv->SavePicture("gl.gif+");
  root [3] glv->SavePicture("gl.gif+");
  root [4] glv->SavePicture("gl.gif+");

  Between each call to glv->SavePicture("gl.gif+"), the GL-Viewer display
  has been modified. Then gl.gif is an amination build from the various
  images displayed in the GL-Viewer.
