204th June 2010  Laurent Garnier
21- G4OpenGLImmediate/StoredQtViewer : Add protection against multiple
22  repaint call. Add protection against resizeGl with bad values
23
243rd June 2010  John Allison  (opengl-V09-03-06)
25- G4OpenGLImmediateSceneHandler: Re-instate
26  // Make sure screen corresponds to graphical database...
27  if (fpViewer) {
28    fpViewer -> SetView ();
29    fpViewer -> ClearView ();
30    fpViewer -> DrawView ();
31  }
32  I was wrong - it *is* necessary.  If not there, events are not refreshed.
33  So this and similar changes below are all back to geant4-09-03, including
34  glFlush, which is still a big performance penalty on Mac's Snow Leopard.
35
363rd June 2010  John Allison  (opengl-V09-03-05)
37- Restored following files to geant4-09-03 in interests of stable behaviour:
38  o G4OpenGLStoredSceneHandler.cc
39    Restored code removed in opengl-V09-03-03:
40  // Make sure screen corresponds to graphical database...
41  if (fpViewer) {
42    fpViewer -> SetView ();
43    fpViewer -> ClearView ();
44    fpViewer -> DrawView ();
45  }
46  o G4OpenGLStoredXViewer.cc:
47    Restore to geant4-09-03.  Restored code removed in opengl-V09-03-03:
48      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
49        DrawDisplayLists ();
50        FinishView ();
51- Note: G4OpenGLImmediateSceneHandler: Same code commented out.  I think
52  it's not necessary for immediate mode.
53
5430th May 2010  John Allison  (opengl-V09-03-04)
55- G4OpenGLSceneHandler: Added AddCompound(const G4VDigi&).
56
5729th May 2010  John Allison  (opengl-V09-03-03)
58- G4OpenGLImmediateSceneHandler.cc, G4OpenGLStoredSceneHandler.cc:
59  Removed the following from ClearTransientStrore (was causing
60  unnecessary drawing and flipping buffers?):
61  // Make sure screen corresponds to graphical database...
62  if (fpViewer) {
63    fpViewer -> SetView ();
64    fpViewer -> ClearView ();
65    fpViewer -> DrawView ();
66  }
67- G4OpenGLStoredXViewer.cc:
68  Commented out as follows in DrawView (was causing extra buffer swap,
69  thus showing bad picture; can't recall why it was introduced):
70      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
71        //DrawDisplayLists ();  ????????? (JA)
72        //FinishView ();        ????????? (JA)

453  o Re-organised display lists on a per-primitive basis, i.e., one
454    display list per primitive.  (This is so that, except for text,
455    the colour - or, rather, intensity - can be brought out of the
456    display list into the TOList (Transient Object List) and
457    controlled for the Display-by-Time feature.  Previously, if more
458    than one primitive were drawn between BeginPrimitives and
459    EndPrimitives, it would finish up all in one display list, colour
460    commands included. Rationalises and fixes a rare bug in the
461    Display-by-Time feature - see August 2006.)
462  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
463    one primoitive to fit with the above re-organisation.
464- Implemented picking for OGLIX.
465
46625th March 2007  John Allison  (opengl-V08-02-03)
467- Fix compiler warnings.
468
4698th February 2007  John Allison  (opengl-V08-02-02)
470- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
471- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
472  .but not switched back.  Not serious, because context was always set
473  before normal drawing.)
474
4759th January 2007  John Allison  (opengl-V08-02-01)
476- Implemented bitmap markers for MarkerSizeType == screen.  (The old
477  polygon implementation remains for MarkerSizeType == world.)
478- Added G4OpenGLBitMapStore to assist the above.
479- G4OpenGLXViewer::CreateGLXContext:
480  o Bug fix: Added missing break in colormap lookup routine.
481
4825th January 2007  John Allison  (opengl-V08-02-00)
483- G4OpenGLSceneHandler.cc:
484  o Followed change of signature of GetLineWidth in visman-V08-02-00.
485  o Minor efficiency improvements.
486
48721st November 2006  John Allison  (opengl-V08-01-09)
488- Fixed compiler warnings.
489
4901st November 2006  John Allison  (opengl-V08-01-08)
491- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
492  actually initiates a print, rather than set a flag for printing.
493
49424th October 2006  John Allison  (opengl-V08-01-07)
495- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
496- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
497
49819th September 2006  John Allison  (opengl-V08-01-06)
499- Added time origin for light front.
500- Added /vis/ogl/set/transparency.
501- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
502
5034th September 2006  John Allison  (opengl-V08-01-05)
504- Implement cutaways.
505- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
506  primitives (see detector being drawn).
507- /vis/oglx/set/printEPS: change parameter default to true.
508
50930th August 2006  John Allison  (opengl-V08-01-04)
510- G4OpenGLSceneHandler:
511  o Implemented line width.
512  o Switched off back face culling when clipping so that the inside of
513    volumes can be seen.
514  o Added CreateSection/CutawayPolyhedron to exploit generic
515    sectioning (DCUT) and cutaways.  Currently not activated due to
516    instabilities in BooleanProcessor.  Local sectioning still active
517    but broken (at least on Mac) due to apparent change in effect of
518    clipping planes (polyhedron edges not reconstructed).
519  o Rationalised calculation of marker size.
520- G4OpenGLStoredSceneHandler:
521  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
522  o Pick up time range from G4VisAttributes.
523- G4OpenGLViewer(Messenger):
524  o Added position and colour to /vis/ogl/set/displayHeadTime.
525  o Added /vis/ogl/set/displayLightFront.
526- G4OpenGLStoredViewer.cc:
527  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
528  o Added position and colour to DisplayHeadTime.
529  o Added DisplayLightFront.
530 
53116th August 2006  John Allison  (opengl-V08-01-03)
532- Corrected Solaris compilation error.
533- Added /vis/ogl/set/fade and displayHeadTime.
534
53514th August 2006  John Allison  (opengl-V08-01-02)
536- Needs visman-V08-01-02.
537- G4OpenGLStored: Implemented display-by-time.  Only available in
538  stored mode at present.  Only implemented for circle, square,
539  polyline and polymarker at present, enough for currently available
540  trajectory models.  Time is communicated via G4AttValues.
541- Added G4OpenGLViewerMessenger.
542- Added /vis/ogl/set/startTime and endTime of displayed objects.
543- All factories: Instantiated G4OpenGLViewerMessenger.
544- G4OpenGLViewer: Added fStart/EndTime.
545- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
546  spewPrimitiveEPS and spewSortedFeedback.
547
54817th July  John Allison  (opengl-V08-01-01)
549- Added /vis/oglx/set/printEPS (prints eps file on every update).
550
5513rd July 2006  John Allison  (opengl-V08-01-00)
552- Elimination of redundant variable doublebuffer and implementation of
553  FinishView in all viewers.
554
55530th May 2006  Joseph Perl  (opengl-V08-00-08)
556- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
557  variable seems to have random behavior and should be assumed false for
558  this viewer.
559
56029th May 2006  Joseph Perl  (opengl-V08-00-07)
561- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
562  Removed common FinishView and instead made separate FinishView for the two different
563  versions of this viewer since each wants a different buffer swapping behaviour.
564
56512th May 2006  John Allison  (opengl-V08-00-06)
566- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
567
56828th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
569- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
570  recomputing transients.
571
57224th April 2006  John Allison  (opengl-V08-00-04)
573- Fixed compilation problem on Windows.
574
57519th April 2006  John Allison  (opengl-V08-00-03)
576- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
577  G4OpenGLImmediateSceneHandler:
578  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
579    greps-V08-00-02).
580  o Migrated to direct access to G4PhysicalVolumeModel.
581- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
582  of display lists in DrawView.
583
58414th March 2006  John Allison  (opengl-V08-00-02)
585- Refined display list building and re-drawing algorithm.
586  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
587  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
588- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
589  re-use algorithm.  In test19 with global culling off, numbers of
590  display lists used are:
591  o 191  No re-use:
592  o  73  Before this change: re-use except replicas (includes parameterised).
593  o  33  After this change: re-use except parameterised and replicas in radius.
594
59526th January 2006  John Allison  (opengl-V08-00-01)
596- Coworks with visman-V08-00-04 (removed fModified).
597- Removed references to fModified.
598- Tidying: Removed unnecessary ClearView.
599- G4OpenGLSceneHandler.cc: Added some (commented out) code for
600  possible future implementation of 2D drawing.
601- G4OpenGLXViewer.cc: Improved exception printing.
602
60311th January 2006  John Allison  (opengl-V08-00-00)
604- Improved efficiency: all DrawView's:
605  o Don't call ClearView.
606  o Set flag so SetView will not be called in ProcessView.
607  o Leave background colour to ClearView.
608- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
609- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
610  for current viewer.
611
61224th November 2005  John Allison  (opengl-V07-01-09)
613- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
614
61522nd November 2005  John Allison  (opengl-V07-01-08)
616- Added G4OpenGLXmViewerMessenger.
617- Corrected text position.
618- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
619
62017th November 2005  Gabriele Cosmo
621- Fixed settings of background style for WIN32 viewers.
622
62313th November 2005  John Allison  (opengl-V07-01-07)
624- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
625
62613th October 2005  John Allison  (opengl-V07-01-06)
627- Allowed any colour background.
628- Implemented non-uniform scaling.
629- Migration to <sstream>.
630
63129th September 2005  John Allison  (opengl-V07-01-05)
632- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
633  scene handler.
634- Re-implemented transparency button in OpenGLXm.
635
63613th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
637- Implemented white background for all OGL viewers.
638- G4OpenGLSceneHandler.cc:
639  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
640  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
641  o Corrected GetTextColour(text).
642  o Corrected GetColour(polyhedron).
643
6445th September 2005  John Allison  (opengl-V07-01-03)
645- Bug fix: stored transparent objects were being lost.
646
6472nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
648- Bug fix: edgeflags problem introduced with smooth shading in
649  opengl-V07-01-00.
650- Implementation of a "better algorithm" for the rendering of
651  transparent polyhedron objects.  It renders all opaque objects
652  first, then renders the transparent objects with the depth buffer in
653  read-only mode (see OpenGL Programming Guide).  It uses the new
654  facility in G4VSceneHandler::ProcessScene for an optional second pass
655  of the run-duration models in the scene.  Note this algorithm is
656  still only an approximation.  It will still give the wrong blended
657  colour if two transparent objects are rendered front first.  For
658  nested transparent objects, this is unfortunate, because
659  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
660  in such a way that mothers come first.  Also, there is no guaranteed
661  relationship between the order of rendering and the depth of two
662  transparent objects if they are at the same level or in different
663  branches of the hierarchy.  Still, the only error will be an
664  incorrect colour - the objects will still give the appearance of
665  transparency, so it's a pretty good algorithm.  (An even better
666  algorithm would be to attempt to render the facets in depth order,
667  deepest first.  But how do you calculate the depth - centre of area,
668  deepest corner?  One can still imagine pathalogical cases that would
669  sometimes give the wrong colour.  Also, for stored mode, the order
670  is fixed in a display list so when the user rotates the view, one
671  would lose the depth ordering.  I think we have to accept that
672  blending in OpenGL is only ever an approximation.  For accurate
673  blending, use RayTracer.)
674
67528th August 2005  John Allison  (opengl-V07-01-01)
676- Half-way implementation of rendering of transparent polyhedron
677  objects.  In this implementation, no account is taken of the order
678  of rendering.  Transparent objects are rendered with depth testing
679  off so that objects behind can still be seen.  But this means that
680  opaque objects in front do not obscure them - and they jolly well
681  should!  A better algorithm is to render all opaque objects first,
682  then render the transparent objects with the depth buffer in
683  read-only mode (see OpenGL Programming Guide).  This is going to
684  take a little more thought - see opengl-V07-01-02.
685
68620th July 2005  John Allison  (opengl-V07-01-00)
687- Introduced smooth shading, taking advantage of hitherto un-noticed
688  feature of HepPolyhedron::GetNextFacet that calculates the normals
689  at each vertex so that curved surfaces are rendered more
690  realistically (Gouraud shading).
691- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
692- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
693  the default window size.  It used to be 400x400, hardcoded in
694  G4OpenGLXmViewer.cc, but now it picks up the
695  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
696  The user may change it on the command line, e.g:
697    /vis/open OGLSXm 500
698  or
699    /vis/viewer/create ! ! 500
700
70130th May 2005  John Allison  (opengl-V07-00-03)
702- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
703  map of vectors in G4OpenGLFontBaseStore.)
704
7054th May 2005  John Allison  (opengl-V07-00-02)
706- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
707  was taken out to prevent recursive calling, but that seems to be OK,
708  and it is needed to implement refresh at end of event/run.)
709
71022nd April 2005  John Allison  (opengl-V07-00-01)
711- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
712  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
713  o In all concrete viewers, added call to CreateFontLists().
714  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
715  o There is no longer a need to implement in the XmViewer, since it
716    now inherits.  Thus the font code now only appears once for X.
717  o Awaiting implementation for WIN32.
718
71917th April 2005  John Allison  (opengl-V07-00-00)
720- Based on vis-V07-00-13.
721- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
722  creates display lists for nominated fonts.  Simple-minded scheme in
723  which each viewer creates its own font display lists for a variety
724  of sizes, which are accessed by the scene handler through a new
725  class, G4OpenGLFontBaseStore.  Affected methods:
726    G4OpenGLXViewer::CreateMainWindow()
727    G4OpenGLXmViewer::CreateMainWindow()
728    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
729
73018th November 2004  John Allison  (opengl-V06-02-07)
731- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
732
73315th November 2004  Guy Barrand
734- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
735  to see trajectories (for example with N03). Correct so that
736  ShowView do a FinishView that does : glFlush, wglSwapBuffer
737  and empty the Windows message queue.
738
73922nd September 2004  John Allison  (opengl-V06-02-06)
740- doxygen output to tmp area.
741- Trap non-regular polyhedrons.
742
74313th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
744- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
745  to allow for porting on CLHEP-1.9.X series.
746
74723rd July 2004  John Allison
748- Draws auxiliary edges if required.
749- Added auxiliary edge button.
750
75116th July 2004  John Allison  (opengl-V06-02-04)
752- Refinements to hidden line, hidden surface removal.
753
75414th July 2004  John Allison  (opengl-V06-02-03)
755- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
756
75713th July 2004  John Allison  (opengl-V06-02-02)
758- Hidden line *and* hidden surface removal now works.
759
7609th July 2004  John Allison  (opengl-V06-02-01)
761- Fixed long-standing problem with hidden line removal.
762- Improved messages on failure to get visual.
763- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
764  systems provided by default anyway, so no effect.
765
7661st July 2004  John Allison  (opengl-V06-02-00)
767- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
768- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
769
77018th June 2004  Gunter Folger (geant4-06-02)
7719th June 2004  Gabriele Cosmo  (vis-V06-01-03)
7727th June 2004  Gabriele Cosmo  (vis-V06-01-02)
773- GNUmakefile and disclaimer changes - see visualization/History.
774
7759th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
776- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
777
7787th April 2004  Guy Barrand
779- visualization/OpenGL/* : use the G4OpenGL.hh file.
780- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
781  the include of gl/gl.h and gl/glu.h that may be platform dependant.
782  It permits to rm some #ifdef WIN32 spread in the code. It opens also
783  the way to the usage of the Apple OpenGL on a Mac.
784
78517th February 2004  John Allison  (opengl-V06-00-00)
786- Fixed bug #581: wrong order of statements in
787  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
788
7894th October 2003  Gabriele Cosmo  (vis-V05-02-01)
790- GNUmakefile:
791  o replaced "digits+hits" with "digits_hits".
792- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
793
79422nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
795- Cosmetic change to regularise names:
796  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
797  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
798
79923rd June 2003  Guy Barrand  (opengl-V05-01-02)
800- Commit a first implementation of G4OpenGLWin32Viewer.
801
80210th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
803- More fixes for warnings in viewers classes.
804- Added inclusion of <windows.h> for WIN32 platforms when GL headers
805  are included.
806
80705th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
808- Fixes for porting compilation on WIN32:
809  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
810  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
811    since declared 'obsolete' in WIN32 platforms.
812
81327th November 2002  John Allison  (vis-V04-01-08)
814- Improved algorithm of CompareForKernelVisit.
815
81611th November 2002  John Allison  (opengl-V04-01-02)
817- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
818- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
819  call default but there as a marker and encourager.
820- Added tracking and digits+hits/hits to GNUmakefile.
821
82216th October 2002  John Allison  (opengl-V04-01-01)
823- Fix for WIN32.  Now compiles but viewer not implemented.
824
82524th June 2002  John Allison  (opengl-V04-01-00)
826- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
827
82810th June 2002  John Allison  (opengl-V04-00-03)
829- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
830
8316th June 2002  John Allison  (opengl-V04-00-02)
832- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
833
83423rd February 2002  John Allison  (opengl-V04-00-01)
835- Changes to encourage compilation on Windows in preparation for
836  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
837  glx.h, unistd.h and assert.h.
838
83924th August 2001  John Allison  (vis-V03-02-13)
840- Limited the printing of warnings in
841  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
842
84314th August 2001  John Allison  (vis-V03-02-11)
844- Improved KernelVisitDecision.
845- Fixed a few small bugs in multiple "stored" viewers, but see next item.
846- There's an outstanding bug in OpenGL Stored.  If there is more than
847  one viewer controlled by a scene handler, after a ClearStore on the
848  scene handler, e.g., with /vis/scene/notifyHandlers, the first
849  viewer to get refreshed should trigger the display list rebuild, but
850  the second need not.  However, when the second viewer's turn comes,
851  the display lists are there, and are called, e.g.,
852  G4OpenGLStoredXViewer::DrawView calls
853  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
854  nothing appears on the screen.  To overcome this there is some
855  temporary code in G4VViewer::NeedKernelVisit which marks *all*
856  viewers to force a rebuild.  To see the symptoms, comment out that
857  temporary code and issue these commands:
858    /vis/verbose c
859    /control/verbose 2
860    /vis/scene/create
861    /vis/scene/add/volume
862    /vis/sceneHandler/create OGLSX
863    /vis/viewer/create ! ! 1
864    /run/beamOn
865    /vis/viewer/create ! ! 1
866    /vis/viewer/select viewer-0

880  One of the viewers is empty.  Curious!!

8829th August 2001  John Allison  (vis-V03-02-10-00)
883- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
884- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
885  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
886  picked up by inheritance anyway.
887- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
888- Corrected order of calling base class functions in
889  G4OpenGLStoredSceneHandler::Begin/EndModeling.
890
89124th July 2001  John Allison  (vis-V03-02-06)
892- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
893
89414th July 2001  John Allison (opengl-V03-02-00)
895- Fixed crash in optimised mode: added Initialise() to viewers so
896  that windows are opened after viewers are fully constructed.
897
8982nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
899- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.

9017th March 2001  John Allison
902- Changed char* to const char* in many places and that gave problems in
903  calls to Xt and Xm.  Hope all's OK.  Differences:

90625th January 2001  John Allison  (opengl-V03-00-00)
907- Implemented running re-calculation of up-vector in the case of "object
908  rotation" (lights move with camera) to prevent "flipping" of view when
909  camera passes through up-vector.  Note that the default is "camera
910  rotation" (lights do not move with camera, i.e., remain fixed relative
911  to object) so the default is that this "flipping" can happen.  To set
912  "object rotation" (lights move with camera) use
913  /vis/lights/move_with_camera true (soon to be
914  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
915  on Rotation Panel in OpenGLXm mode.
916- Changed some objects to references for efficiency.  E.g.:
917  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
918
91922nd May 2000  John Allison  (opengl-V01-01-00)
920- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
921  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
922    static XVisualInfo* vi_single_buffer;
923    static XVisualInfo* vi_double_buffer;
924- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
925  G4OpenGLXViewer.
926- Protected double deletion of window in destructors of G4OpenGLXmViewer
927  and G4OpenGLXViewer (Guy Barrand).
928- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
929- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
930  constructors.
