21- G4OpenGLSceneHandler: Added AddCompound(const G4VDigi&).
22
2329th May 2010  John Allison  (opengl-V09-03-03)
24- G4OpenGLImmediateSceneHandler.cc, G4OpenGLStoredSceneHandler.cc:
25  Removed the following from ClearTransientStrore (was causing
26  unnecessary drawing and flipping buffers?):
27  // Make sure screen corresponds to graphical database...
28  if (fpViewer) {
29    fpViewer -> SetView ();
30    fpViewer -> ClearView ();
31    fpViewer -> DrawView ();
32  }
33- G4OpenGLStoredXViewer.cc:
34  Commented out as follows in DrawView (was causing extra buffer swap,
35  thus showing bad picture; can't recall why it was introduced):
36      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
37        //DrawDisplayLists ();  ????????? (JA)
38        //FinishView ();        ????????? (JA)

416
4173rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
418- G4OpenGLStoredSceneHandler:
419  o Re-organised display lists on a per-primitive basis, i.e., one
420    display list per primitive.  (This is so that, except for text,
421    the colour - or, rather, intensity - can be brought out of the
422    display list into the TOList (Transient Object List) and
423    controlled for the Display-by-Time feature.  Previously, if more
424    than one primitive were drawn between BeginPrimitives and
425    EndPrimitives, it would finish up all in one display list, colour
426    commands included. Rationalises and fixes a rare bug in the
427    Display-by-Time feature - see August 2006.)
428  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
429    one primoitive to fit with the above re-organisation.
430- Implemented picking for OGLIX.
431
43225th March 2007  John Allison  (opengl-V08-02-03)

4358th February 2007  John Allison  (opengl-V08-02-02)
436- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
437- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
438  .but not switched back.  Not serious, because context was always set
439  before normal drawing.)
440
4419th January 2007  John Allison  (opengl-V08-02-01)
442- Implemented bitmap markers for MarkerSizeType == screen.  (The old
443  polygon implementation remains for MarkerSizeType == world.)
444- Added G4OpenGLBitMapStore to assist the above.
445- G4OpenGLXViewer::CreateGLXContext:
446  o Bug fix: Added missing break in colormap lookup routine.
447
4485th January 2007  John Allison  (opengl-V08-02-00)
449- G4OpenGLSceneHandler.cc:
450  o Followed change of signature of GetLineWidth in visman-V08-02-00.
451  o Minor efficiency improvements.
452
45321st November 2006  John Allison  (opengl-V08-01-09)
454- Fixed compiler warnings.
455
4561st November 2006  John Allison  (opengl-V08-01-08)
457- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
458  actually initiates a print, rather than set a flag for printing.
459
46024th October 2006  John Allison  (opengl-V08-01-07)
461- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
462- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
463
46419th September 2006  John Allison  (opengl-V08-01-06)
465- Added time origin for light front.
466- Added /vis/ogl/set/transparency.
467- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
468
4694th September 2006  John Allison  (opengl-V08-01-05)
470- Implement cutaways.
471- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
472  primitives (see detector being drawn).
473- /vis/oglx/set/printEPS: change parameter default to true.
474
47530th August 2006  John Allison  (opengl-V08-01-04)
476- G4OpenGLSceneHandler:
477  o Implemented line width.
478  o Switched off back face culling when clipping so that the inside of
479    volumes can be seen.
480  o Added CreateSection/CutawayPolyhedron to exploit generic
481    sectioning (DCUT) and cutaways.  Currently not activated due to
482    instabilities in BooleanProcessor.  Local sectioning still active
483    but broken (at least on Mac) due to apparent change in effect of
484    clipping planes (polyhedron edges not reconstructed).
485  o Rationalised calculation of marker size.
486- G4OpenGLStoredSceneHandler:
487  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
488  o Pick up time range from G4VisAttributes.
489- G4OpenGLViewer(Messenger):
490  o Added position and colour to /vis/ogl/set/displayHeadTime.
491  o Added /vis/ogl/set/displayLightFront.
492- G4OpenGLStoredViewer.cc:
493  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
494  o Added position and colour to DisplayHeadTime.
495  o Added DisplayLightFront.
496 
49716th August 2006  John Allison  (opengl-V08-01-03)
498- Corrected Solaris compilation error.
499- Added /vis/ogl/set/fade and displayHeadTime.
500
50114th August 2006  John Allison  (opengl-V08-01-02)
502- Needs visman-V08-01-02.
503- G4OpenGLStored: Implemented display-by-time.  Only available in
504  stored mode at present.  Only implemented for circle, square,
505  polyline and polymarker at present, enough for currently available
506  trajectory models.  Time is communicated via G4AttValues.
507- Added G4OpenGLViewerMessenger.
508- Added /vis/ogl/set/startTime and endTime of displayed objects.
509- All factories: Instantiated G4OpenGLViewerMessenger.
510- G4OpenGLViewer: Added fStart/EndTime.
511- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
512  spewPrimitiveEPS and spewSortedFeedback.
513
51417th July  John Allison  (opengl-V08-01-01)
515- Added /vis/oglx/set/printEPS (prints eps file on every update).
516
5173rd July 2006  John Allison  (opengl-V08-01-00)
518- Elimination of redundant variable doublebuffer and implementation of
519  FinishView in all viewers.
520
52130th May 2006  Joseph Perl  (opengl-V08-00-08)
522- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
523  variable seems to have random behavior and should be assumed false for
524  this viewer.
525
52629th May 2006  Joseph Perl  (opengl-V08-00-07)
527- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
528  Removed common FinishView and instead made separate FinishView for the two different
529  versions of this viewer since each wants a different buffer swapping behaviour.
530
53112th May 2006  John Allison  (opengl-V08-00-06)
532- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
533
53428th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
535- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
536  recomputing transients.
537
53824th April 2006  John Allison  (opengl-V08-00-04)
539- Fixed compilation problem on Windows.
540
54119th April 2006  John Allison  (opengl-V08-00-03)
542- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
543  G4OpenGLImmediateSceneHandler:
544  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
545    greps-V08-00-02).
546  o Migrated to direct access to G4PhysicalVolumeModel.
547- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
548  of display lists in DrawView.
549
55014th March 2006  John Allison  (opengl-V08-00-02)
551- Refined display list building and re-drawing algorithm.
552  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
553  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
554- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
555  re-use algorithm.  In test19 with global culling off, numbers of
556  display lists used are:
557  o 191  No re-use:
558  o  73  Before this change: re-use except replicas (includes parameterised).
559  o  33  After this change: re-use except parameterised and replicas in radius.
560
56126th January 2006  John Allison  (opengl-V08-00-01)
562- Coworks with visman-V08-00-04 (removed fModified).
563- Removed references to fModified.
564- Tidying: Removed unnecessary ClearView.
565- G4OpenGLSceneHandler.cc: Added some (commented out) code for
566  possible future implementation of 2D drawing.
567- G4OpenGLXViewer.cc: Improved exception printing.
568
56911th January 2006  John Allison  (opengl-V08-00-00)
570- Improved efficiency: all DrawView's:
571  o Don't call ClearView.
572  o Set flag so SetView will not be called in ProcessView.
573  o Leave background colour to ClearView.
574- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
575- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
576  for current viewer.
577
57824th November 2005  John Allison  (opengl-V07-01-09)
579- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
580
58122nd November 2005  John Allison  (opengl-V07-01-08)
582- Added G4OpenGLXmViewerMessenger.
583- Corrected text position.
584- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
585
58617th November 2005  Gabriele Cosmo
587- Fixed settings of background style for WIN32 viewers.
588
58913th November 2005  John Allison  (opengl-V07-01-07)
590- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
591
59213th October 2005  John Allison  (opengl-V07-01-06)
593- Allowed any colour background.
594- Implemented non-uniform scaling.
595- Migration to <sstream>.
596
59729th September 2005  John Allison  (opengl-V07-01-05)
598- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
599  scene handler.
600- Re-implemented transparency button in OpenGLXm.
601
60213th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
603- Implemented white background for all OGL viewers.
604- G4OpenGLSceneHandler.cc:
605  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
606  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
607  o Corrected GetTextColour(text).
608  o Corrected GetColour(polyhedron).
609
6105th September 2005  John Allison  (opengl-V07-01-03)
611- Bug fix: stored transparent objects were being lost.
612
6132nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
614- Bug fix: edgeflags problem introduced with smooth shading in
615  opengl-V07-01-00.
616- Implementation of a "better algorithm" for the rendering of
617  transparent polyhedron objects.  It renders all opaque objects
618  first, then renders the transparent objects with the depth buffer in
619  read-only mode (see OpenGL Programming Guide).  It uses the new
620  facility in G4VSceneHandler::ProcessScene for an optional second pass
621  of the run-duration models in the scene.  Note this algorithm is
622  still only an approximation.  It will still give the wrong blended
623  colour if two transparent objects are rendered front first.  For
624  nested transparent objects, this is unfortunate, because
625  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
626  in such a way that mothers come first.  Also, there is no guaranteed
627  relationship between the order of rendering and the depth of two
628  transparent objects if they are at the same level or in different
629  branches of the hierarchy.  Still, the only error will be an
630  incorrect colour - the objects will still give the appearance of
631  transparency, so it's a pretty good algorithm.  (An even better
632  algorithm would be to attempt to render the facets in depth order,
633  deepest first.  But how do you calculate the depth - centre of area,
634  deepest corner?  One can still imagine pathalogical cases that would
635  sometimes give the wrong colour.  Also, for stored mode, the order
636  is fixed in a display list so when the user rotates the view, one
637  would lose the depth ordering.  I think we have to accept that
638  blending in OpenGL is only ever an approximation.  For accurate
639  blending, use RayTracer.)
640
64128th August 2005  John Allison  (opengl-V07-01-01)
642- Half-way implementation of rendering of transparent polyhedron
643  objects.  In this implementation, no account is taken of the order
644  of rendering.  Transparent objects are rendered with depth testing
645  off so that objects behind can still be seen.  But this means that
646  opaque objects in front do not obscure them - and they jolly well
647  should!  A better algorithm is to render all opaque objects first,
648  then render the transparent objects with the depth buffer in
649  read-only mode (see OpenGL Programming Guide).  This is going to
650  take a little more thought - see opengl-V07-01-02.
651
65220th July 2005  John Allison  (opengl-V07-01-00)
653- Introduced smooth shading, taking advantage of hitherto un-noticed
654  feature of HepPolyhedron::GetNextFacet that calculates the normals
655  at each vertex so that curved surfaces are rendered more
656  realistically (Gouraud shading).
657- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
658- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
659  the default window size.  It used to be 400x400, hardcoded in
660  G4OpenGLXmViewer.cc, but now it picks up the
661  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
662  The user may change it on the command line, e.g:
663    /vis/open OGLSXm 500
664  or
665    /vis/viewer/create ! ! 500
666
66730th May 2005  John Allison  (opengl-V07-00-03)
668- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
669  map of vectors in G4OpenGLFontBaseStore.)
670
6714th May 2005  John Allison  (opengl-V07-00-02)
672- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
673  was taken out to prevent recursive calling, but that seems to be OK,
674  and it is needed to implement refresh at end of event/run.)
675
67622nd April 2005  John Allison  (opengl-V07-00-01)
677- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
678  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
679  o In all concrete viewers, added call to CreateFontLists().
680  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
681  o There is no longer a need to implement in the XmViewer, since it
682    now inherits.  Thus the font code now only appears once for X.
683  o Awaiting implementation for WIN32.
684
68517th April 2005  John Allison  (opengl-V07-00-00)
686- Based on vis-V07-00-13.
687- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
688  creates display lists for nominated fonts.  Simple-minded scheme in
689  which each viewer creates its own font display lists for a variety
690  of sizes, which are accessed by the scene handler through a new
691  class, G4OpenGLFontBaseStore.  Affected methods:
692    G4OpenGLXViewer::CreateMainWindow()
693    G4OpenGLXmViewer::CreateMainWindow()
694    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
695
69618th November 2004  John Allison  (opengl-V06-02-07)
697- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
698
69915th November 2004  Guy Barrand
700- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
701  to see trajectories (for example with N03). Correct so that
702  ShowView do a FinishView that does : glFlush, wglSwapBuffer
703  and empty the Windows message queue.
704
70522nd September 2004  John Allison  (opengl-V06-02-06)
706- doxygen output to tmp area.
707- Trap non-regular polyhedrons.
708
70913th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
710- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
711  to allow for porting on CLHEP-1.9.X series.
712
71323rd July 2004  John Allison
714- Draws auxiliary edges if required.
715- Added auxiliary edge button.
716
71716th July 2004  John Allison  (opengl-V06-02-04)
718- Refinements to hidden line, hidden surface removal.
719
72014th July 2004  John Allison  (opengl-V06-02-03)
721- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
722
72313th July 2004  John Allison  (opengl-V06-02-02)
724- Hidden line *and* hidden surface removal now works.
725
7269th July 2004  John Allison  (opengl-V06-02-01)
727- Fixed long-standing problem with hidden line removal.
728- Improved messages on failure to get visual.
729- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
730  systems provided by default anyway, so no effect.
731
7321st July 2004  John Allison  (opengl-V06-02-00)
733- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
734- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
735
73618th June 2004  Gunter Folger (geant4-06-02)
7379th June 2004  Gabriele Cosmo  (vis-V06-01-03)
7387th June 2004  Gabriele Cosmo  (vis-V06-01-02)
739- GNUmakefile and disclaimer changes - see visualization/History.
740
7419th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
742- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
743
7447th April 2004  Guy Barrand
745- visualization/OpenGL/* : use the G4OpenGL.hh file.
746- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
747  the include of gl/gl.h and gl/glu.h that may be platform dependant.
748  It permits to rm some #ifdef WIN32 spread in the code. It opens also
749  the way to the usage of the Apple OpenGL on a Mac.
750
75117th February 2004  John Allison  (opengl-V06-00-00)
752- Fixed bug #581: wrong order of statements in
753  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
754
7554th October 2003  Gabriele Cosmo  (vis-V05-02-01)
756- GNUmakefile:
757  o replaced "digits+hits" with "digits_hits".
758- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
759
76022nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
761- Cosmetic change to regularise names:
762  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
763  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
764
76523rd June 2003  Guy Barrand  (opengl-V05-01-02)
766- Commit a first implementation of G4OpenGLWin32Viewer.
767
76810th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
769- More fixes for warnings in viewers classes.
770- Added inclusion of <windows.h> for WIN32 platforms when GL headers
771  are included.
772
77305th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
774- Fixes for porting compilation on WIN32:
775  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
776  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
777    since declared 'obsolete' in WIN32 platforms.
778
77927th November 2002  John Allison  (vis-V04-01-08)
780- Improved algorithm of CompareForKernelVisit.
781
78211th November 2002  John Allison  (opengl-V04-01-02)
783- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
784- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
785  call default but there as a marker and encourager.
786- Added tracking and digits+hits/hits to GNUmakefile.
787
78816th October 2002  John Allison  (opengl-V04-01-01)
789- Fix for WIN32.  Now compiles but viewer not implemented.
790
79124th June 2002  John Allison  (opengl-V04-01-00)
792- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
793
79410th June 2002  John Allison  (opengl-V04-00-03)
795- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
796
7976th June 2002  John Allison  (opengl-V04-00-02)
798- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
799
80023rd February 2002  John Allison  (opengl-V04-00-01)
801- Changes to encourage compilation on Windows in preparation for
802  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
803  glx.h, unistd.h and assert.h.
804
80524th August 2001  John Allison  (vis-V03-02-13)
806- Limited the printing of warnings in
807  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
808
80914th August 2001  John Allison  (vis-V03-02-11)
810- Improved KernelVisitDecision.
811- Fixed a few small bugs in multiple "stored" viewers, but see next item.
812- There's an outstanding bug in OpenGL Stored.  If there is more than
813  one viewer controlled by a scene handler, after a ClearStore on the
814  scene handler, e.g., with /vis/scene/notifyHandlers, the first
815  viewer to get refreshed should trigger the display list rebuild, but
816  the second need not.  However, when the second viewer's turn comes,
817  the display lists are there, and are called, e.g.,
818  G4OpenGLStoredXViewer::DrawView calls
819  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
820  nothing appears on the screen.  To overcome this there is some
821  temporary code in G4VViewer::NeedKernelVisit which marks *all*
822  viewers to force a rebuild.  To see the symptoms, comment out that
823  temporary code and issue these commands:
824    /vis/verbose c
825    /control/verbose 2
826    /vis/scene/create
827    /vis/scene/add/volume
828    /vis/sceneHandler/create OGLSX
829    /vis/viewer/create ! ! 1
830    /run/beamOn
831    /vis/viewer/create ! ! 1
832    /vis/viewer/select viewer-0
833    /vis/viewer/viewpointThetaPhi 20 20
834    /vis/viewer/select viewer-1
835    /vis/viewer/viewpointThetaPhi 40 40
836    /vis/viewer/set/style surface
837    /vis/viewer/refresh
838    /vis/viewer/select viewer-0
839    /vis/viewer/refresh
840    /vis/viewer/select viewer-1
841    /vis/viewer/set/style wireframe
842    /vis/scene/notifyHandlers
843  You may have to do this too:
844    /vis/viewer/select viewer-0
845    /vis/scene/notifyHandlers
846  One of the viewers is empty.  Curious!!
847
8489th August 2001  John Allison  (vis-V03-02-10-00)
849- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
850- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
851  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
852  picked up by inheritance anyway.
853- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
854- Corrected order of calling base class functions in
855  G4OpenGLStoredSceneHandler::Begin/EndModeling.
856
85724th July 2001  John Allison  (vis-V03-02-06)
858- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
859
86014th July 2001  John Allison (opengl-V03-02-00)
861- Fixed crash in optimised mode: added Initialise() to viewers so
862  that windows are opened after viewers are fully constructed.
863
8642nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
865- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
866

868- Changed char* to const char* in many places and that gave problems in
869  calls to Xt and Xm.  Hope all's OK.  Differences:

873- Implemented running re-calculation of up-vector in the case of "object
874  rotation" (lights move with camera) to prevent "flipping" of view when
875  camera passes through up-vector.  Note that the default is "camera
876  rotation" (lights do not move with camera, i.e., remain fixed relative
877  to object) so the default is that this "flipping" can happen.  To set
878  "object rotation" (lights move with camera) use
879  /vis/lights/move_with_camera true (soon to be
880  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
881  on Rotation Panel in OpenGLXm mode.
882- Changed some objects to references for efficiency.  E.g.:
883  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();

886- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
887  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
888    static XVisualInfo* vi_single_buffer;
889    static XVisualInfo* vi_double_buffer;
890- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
891  G4OpenGLXViewer.
892- Protected double deletion of window in destructors of G4OpenGLXmViewer
893  and G4OpenGLXViewer (Guy Barrand).
894- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
895- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
896  constructors.
