342  o Correct path /vis/ogl/set/printMode.
343  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
344    and "/vis/ogl/printEPS").
345
3468th May 2007  John Allison  (opengl-V08-02-06)
347- Moved vectored PostScript printing to G4OpenGLViewer.
348- /vis/ogl/printEPS should work for all viewers, including Win32.
349- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
350  effective on X windows (and still somewhat buggy).
351
3524th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
353- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
354  for OGL*Win32.  Still doesn't work for OGL*Xm.
355
3563rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
357- G4OpenGLStoredSceneHandler:
358  o Re-organised display lists on a per-primitive basis, i.e., one
359    display list per primitive.  (This is so that, except for text,
360    the colour - or, rather, intensity - can be brought out of the
361    display list into the TOList (Transient Object List) and
362    controlled for the Display-by-Time feature.  Previously, if more
363    than one primitive were drawn between BeginPrimitives and
364    EndPrimitives, it would finish up all in one display list, colour
365    commands included. Rationalises and fixes a rare bug in the
366    Display-by-Time feature - see August 2006.)
367  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
368    one primoitive to fit with the above re-organisation.
369- Implemented picking for OGLIX.
370
37125th March 2007  John Allison  (opengl-V08-02-03)
372- Fix compiler warnings.
373
3748th February 2007  John Allison  (opengl-V08-02-02)
375- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
376- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
377  .but not switched back.  Not serious, because context was always set
378  before normal drawing.)
379
3809th January 2007  John Allison  (opengl-V08-02-01)
381- Implemented bitmap markers for MarkerSizeType == screen.  (The old
382  polygon implementation remains for MarkerSizeType == world.)
383- Added G4OpenGLBitMapStore to assist the above.
384- G4OpenGLXViewer::CreateGLXContext:
385  o Bug fix: Added missing break in colormap lookup routine.
386
3875th January 2007  John Allison  (opengl-V08-02-00)
388- G4OpenGLSceneHandler.cc:
389  o Followed change of signature of GetLineWidth in visman-V08-02-00.

394
3951st November 2006  John Allison  (opengl-V08-01-08)
396- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
397  actually initiates a print, rather than set a flag for printing.
398
39924th October 2006  John Allison  (opengl-V08-01-07)
400- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

404- Added time origin for light front.
405- Added /vis/ogl/set/transparency.
406- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
407
4084th September 2006  John Allison  (opengl-V08-01-05)
409- Implement cutaways.
410- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
411  primitives (see detector being drawn).
412- /vis/oglx/set/printEPS: change parameter default to true.
413
41430th August 2006  John Allison  (opengl-V08-01-04)
415- G4OpenGLSceneHandler:
416  o Implemented line width.
417  o Switched off back face culling when clipping so that the inside of
418    volumes can be seen.
419  o Added CreateSection/CutawayPolyhedron to exploit generic
420    sectioning (DCUT) and cutaways.  Currently not activated due to
421    instabilities in BooleanProcessor.  Local sectioning still active
422    but broken (at least on Mac) due to apparent change in effect of
423    clipping planes (polyhedron edges not reconstructed).
424  o Rationalised calculation of marker size.
425- G4OpenGLStoredSceneHandler:
426  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
427  o Pick up time range from G4VisAttributes.
428- G4OpenGLViewer(Messenger):
429  o Added position and colour to /vis/ogl/set/displayHeadTime.
430  o Added /vis/ogl/set/displayLightFront.
431- G4OpenGLStoredViewer.cc:
432  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
433  o Added position and colour to DisplayHeadTime.
434  o Added DisplayLightFront.
435 
43616th August 2006  John Allison  (opengl-V08-01-03)
437- Corrected Solaris compilation error.
438- Added /vis/ogl/set/fade and displayHeadTime.
439
44014th August 2006  John Allison  (opengl-V08-01-02)
441- Needs visman-V08-01-02.
442- G4OpenGLStored: Implemented display-by-time.  Only available in
443  stored mode at present.  Only implemented for circle, square,
444  polyline and polymarker at present, enough for currently available
445  trajectory models.  Time is communicated via G4AttValues.
446- Added G4OpenGLViewerMessenger.
447- Added /vis/ogl/set/startTime and endTime of displayed objects.
448- All factories: Instantiated G4OpenGLViewerMessenger.
449- G4OpenGLViewer: Added fStart/EndTime.
450- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
451  spewPrimitiveEPS and spewSortedFeedback.
452
45317th July  John Allison  (opengl-V08-01-01)
454- Added /vis/oglx/set/printEPS (prints eps file on every update).
455
4563rd July 2006  John Allison  (opengl-V08-01-00)
457- Elimination of redundant variable doublebuffer and implementation of
458  FinishView in all viewers.
459
46030th May 2006  Joseph Perl  (opengl-V08-00-08)
461- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
462  variable seems to have random behavior and should be assumed false for
463  this viewer.
464
46529th May 2006  Joseph Perl  (opengl-V08-00-07)
466- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
467  Removed common FinishView and instead made separate FinishView for the two different
468  versions of this viewer since each wants a different buffer swapping behaviour.
469
47012th May 2006  John Allison  (opengl-V08-00-06)
471- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
472
47328th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
474- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
475  recomputing transients.
476
47724th April 2006  John Allison  (opengl-V08-00-04)
478- Fixed compilation problem on Windows.
479
48019th April 2006  John Allison  (opengl-V08-00-03)
481- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
482  G4OpenGLImmediateSceneHandler:
483  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
484    greps-V08-00-02).
485  o Migrated to direct access to G4PhysicalVolumeModel.
486- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
487  of display lists in DrawView.
488
48914th March 2006  John Allison  (opengl-V08-00-02)
490- Refined display list building and re-drawing algorithm.
491  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
492  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
493- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
494  re-use algorithm.  In test19 with global culling off, numbers of
495  display lists used are:
496  o 191  No re-use:
497  o  73  Before this change: re-use except replicas (includes parameterised).
498  o  33  After this change: re-use except parameterised and replicas in radius.
499
50026th January 2006  John Allison  (opengl-V08-00-01)
501- Coworks with visman-V08-00-04 (removed fModified).
502- Removed references to fModified.
503- Tidying: Removed unnecessary ClearView.
504- G4OpenGLSceneHandler.cc: Added some (commented out) code for
505  possible future implementation of 2D drawing.
506- G4OpenGLXViewer.cc: Improved exception printing.
507
50811th January 2006  John Allison  (opengl-V08-00-00)
509- Improved efficiency: all DrawView's:
510  o Don't call ClearView.
511  o Set flag so SetView will not be called in ProcessView.
512  o Leave background colour to ClearView.
513- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
514- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
515  for current viewer.
516
51724th November 2005  John Allison  (opengl-V07-01-09)
518- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
519
52022nd November 2005  John Allison  (opengl-V07-01-08)
521- Added G4OpenGLXmViewerMessenger.
522- Corrected text position.
523- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
524
52517th November 2005  Gabriele Cosmo
526- Fixed settings of background style for WIN32 viewers.
527
52813th November 2005  John Allison  (opengl-V07-01-07)
529- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
530
53113th October 2005  John Allison  (opengl-V07-01-06)
532- Allowed any colour background.
533- Implemented non-uniform scaling.
534- Migration to <sstream>.
535
53629th September 2005  John Allison  (opengl-V07-01-05)
537- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
538  scene handler.
539- Re-implemented transparency button in OpenGLXm.
540
54113th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
542- Implemented white background for all OGL viewers.
543- G4OpenGLSceneHandler.cc:
544  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
545  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
546  o Corrected GetTextColour(text).
547  o Corrected GetColour(polyhedron).
548
5495th September 2005  John Allison  (opengl-V07-01-03)
550- Bug fix: stored transparent objects were being lost.
551
5522nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
553- Bug fix: edgeflags problem introduced with smooth shading in
554  opengl-V07-01-00.
555- Implementation of a "better algorithm" for the rendering of
556  transparent polyhedron objects.  It renders all opaque objects
557  first, then renders the transparent objects with the depth buffer in
558  read-only mode (see OpenGL Programming Guide).  It uses the new
559  facility in G4VSceneHandler::ProcessScene for an optional second pass
560  of the run-duration models in the scene.  Note this algorithm is
561  still only an approximation.  It will still give the wrong blended
562  colour if two transparent objects are rendered front first.  For
563  nested transparent objects, this is unfortunate, because
564  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
565  in such a way that mothers come first.  Also, there is no guaranteed
566  relationship between the order of rendering and the depth of two
567  transparent objects if they are at the same level or in different
568  branches of the hierarchy.  Still, the only error will be an
569  incorrect colour - the objects will still give the appearance of
570  transparency, so it's a pretty good algorithm.  (An even better
571  algorithm would be to attempt to render the facets in depth order,
572  deepest first.  But how do you calculate the depth - centre of area,
573  deepest corner?  One can still imagine pathalogical cases that would
574  sometimes give the wrong colour.  Also, for stored mode, the order
575  is fixed in a display list so when the user rotates the view, one
576  would lose the depth ordering.  I think we have to accept that
577  blending in OpenGL is only ever an approximation.  For accurate
578  blending, use RayTracer.)
579
58028th August 2005  John Allison  (opengl-V07-01-01)
581- Half-way implementation of rendering of transparent polyhedron
582  objects.  In this implementation, no account is taken of the order
583  of rendering.  Transparent objects are rendered with depth testing
584  off so that objects behind can still be seen.  But this means that
585  opaque objects in front do not obscure them - and they jolly well
586  should!  A better algorithm is to render all opaque objects first,
587  then render the transparent objects with the depth buffer in
588  read-only mode (see OpenGL Programming Guide).  This is going to
589  take a little more thought - see opengl-V07-01-02.
590
59120th July 2005  John Allison  (opengl-V07-01-00)
592- Introduced smooth shading, taking advantage of hitherto un-noticed
593  feature of HepPolyhedron::GetNextFacet that calculates the normals
594  at each vertex so that curved surfaces are rendered more
595  realistically (Gouraud shading).
596- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
597- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
598  the default window size.  It used to be 400x400, hardcoded in
599  G4OpenGLXmViewer.cc, but now it picks up the
600  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
601  The user may change it on the command line, e.g:
602    /vis/open OGLSXm 500
603  or
604    /vis/viewer/create ! ! 500
605
60630th May 2005  John Allison  (opengl-V07-00-03)
607- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
608  map of vectors in G4OpenGLFontBaseStore.)
609
6104th May 2005  John Allison  (opengl-V07-00-02)
611- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
612  was taken out to prevent recursive calling, but that seems to be OK,
613  and it is needed to implement refresh at end of event/run.)
614
61522nd April 2005  John Allison  (opengl-V07-00-01)
616- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
617  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
618  o In all concrete viewers, added call to CreateFontLists().
619  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
620  o There is no longer a need to implement in the XmViewer, since it
621    now inherits.  Thus the font code now only appears once for X.
622  o Awaiting implementation for WIN32.
623
62417th April 2005  John Allison  (opengl-V07-00-00)
625- Based on vis-V07-00-13.
626- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
627  creates display lists for nominated fonts.  Simple-minded scheme in
628  which each viewer creates its own font display lists for a variety
629  of sizes, which are accessed by the scene handler through a new
630  class, G4OpenGLFontBaseStore.  Affected methods:
631    G4OpenGLXViewer::CreateMainWindow()
632    G4OpenGLXmViewer::CreateMainWindow()
633    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
634
63518th November 2004  John Allison  (opengl-V06-02-07)
636- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
637
63815th November 2004  Guy Barrand
639- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
640  to see trajectories (for example with N03). Correct so that
641  ShowView do a FinishView that does : glFlush, wglSwapBuffer
642  and empty the Windows message queue.
643
64422nd September 2004  John Allison  (opengl-V06-02-06)
645- doxygen output to tmp area.
646- Trap non-regular polyhedrons.
647
64813th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
649- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
650  to allow for porting on CLHEP-1.9.X series.
651
65223rd July 2004  John Allison
653- Draws auxiliary edges if required.
654- Added auxiliary edge button.
655
65616th July 2004  John Allison  (opengl-V06-02-04)
657- Refinements to hidden line, hidden surface removal.
658
65914th July 2004  John Allison  (opengl-V06-02-03)
660- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
661
66213th July 2004  John Allison  (opengl-V06-02-02)
663- Hidden line *and* hidden surface removal now works.
664
6659th July 2004  John Allison  (opengl-V06-02-01)
666- Fixed long-standing problem with hidden line removal.
667- Improved messages on failure to get visual.
668- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
669  systems provided by default anyway, so no effect.
670
6711st July 2004  John Allison  (opengl-V06-02-00)
672- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
673- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
674
67518th June 2004  Gunter Folger (geant4-06-02)
6769th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6777th June 2004  Gabriele Cosmo  (vis-V06-01-02)
678- GNUmakefile and disclaimer changes - see visualization/History.
679
6809th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
681- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
682
6837th April 2004  Guy Barrand
684- visualization/OpenGL/* : use the G4OpenGL.hh file.
685- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
686  the include of gl/gl.h and gl/glu.h that may be platform dependant.
687  It permits to rm some #ifdef WIN32 spread in the code. It opens also
688  the way to the usage of the Apple OpenGL on a Mac.
689
69017th February 2004  John Allison  (opengl-V06-00-00)
691- Fixed bug #581: wrong order of statements in
692  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
693
6944th October 2003  Gabriele Cosmo  (vis-V05-02-01)
695- GNUmakefile:
696  o replaced "digits+hits" with "digits_hits".
697- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
698
69922nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
700- Cosmetic change to regularise names:
701  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
702  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
703
70423rd June 2003  Guy Barrand  (opengl-V05-01-02)
705- Commit a first implementation of G4OpenGLWin32Viewer.
706
70710th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
708- More fixes for warnings in viewers classes.
709- Added inclusion of <windows.h> for WIN32 platforms when GL headers
710  are included.
711
71205th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
713- Fixes for porting compilation on WIN32:
714  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
715  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
716    since declared 'obsolete' in WIN32 platforms.
717
71827th November 2002  John Allison  (vis-V04-01-08)
719- Improved algorithm of CompareForKernelVisit.
720
72111th November 2002  John Allison  (opengl-V04-01-02)
722- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
723- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
724  call default but there as a marker and encourager.
725- Added tracking and digits+hits/hits to GNUmakefile.
726
72716th October 2002  John Allison  (opengl-V04-01-01)
728- Fix for WIN32.  Now compiles but viewer not implemented.
729
73024th June 2002  John Allison  (opengl-V04-01-00)
731- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
732
73310th June 2002  John Allison  (opengl-V04-00-03)
734- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
735
7366th June 2002  John Allison  (opengl-V04-00-02)
737- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
738
73923rd February 2002  John Allison  (opengl-V04-00-01)
740- Changes to encourage compilation on Windows in preparation for
741  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
742  glx.h, unistd.h and assert.h.
743
74424th August 2001  John Allison  (vis-V03-02-13)
745- Limited the printing of warnings in
746  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
747
74814th August 2001  John Allison  (vis-V03-02-11)
749- Improved KernelVisitDecision.
750- Fixed a few small bugs in multiple "stored" viewers, but see next item.
751- There's an outstanding bug in OpenGL Stored.  If there is more than
752  one viewer controlled by a scene handler, after a ClearStore on the
753  scene handler, e.g., with /vis/scene/notifyHandlers, the first
754  viewer to get refreshed should trigger the display list rebuild, but
755  the second need not.  However, when the second viewer's turn comes,
756  the display lists are there, and are called, e.g.,
757  G4OpenGLStoredXViewer::DrawView calls
758  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
759  nothing appears on the screen.  To overcome this there is some
760  temporary code in G4VViewer::NeedKernelVisit which marks *all*
761  viewers to force a rebuild.  To see the symptoms, comment out that
762  temporary code and issue these commands:
763    /vis/verbose c
764    /control/verbose 2
765    /vis/scene/create
766    /vis/scene/add/volume
767    /vis/sceneHandler/create OGLSX
768    /vis/viewer/create ! ! 1
769    /run/beamOn
770    /vis/viewer/create ! ! 1
771    /vis/viewer/select viewer-0
772    /vis/viewer/viewpointThetaPhi 20 20
773    /vis/viewer/select viewer-1
774    /vis/viewer/viewpointThetaPhi 40 40
775    /vis/viewer/set/style surface
776    /vis/viewer/refresh
777    /vis/viewer/select viewer-0
778    /vis/viewer/refresh
779    /vis/viewer/select viewer-1
780    /vis/viewer/set/style wireframe
781    /vis/scene/notifyHandlers
782  You may have to do this too:
783    /vis/viewer/select viewer-0
784    /vis/scene/notifyHandlers
785  One of the viewers is empty.  Curious!!
786
7879th August 2001  John Allison  (vis-V03-02-10-00)
788- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
789- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
790  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
791  picked up by inheritance anyway.
792- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
793- Corrected order of calling base class functions in
794  G4OpenGLStoredSceneHandler::Begin/EndModeling.
795
79624th July 2001  John Allison  (vis-V03-02-06)
797- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
798
79914th July 2001  John Allison (opengl-V03-02-00)
800- Fixed crash in optimised mode: added Initialise() to viewers so
801  that windows are opened after viewers are fully constructed.
802
8032nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
804- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
805
8067th March 2001  John Allison
807- Changed char* to const char* in many places and that gave problems in
808  calls to Xt and Xm.  Hope all's OK.  Differences:
809    cvs diff -r vis-V03-00-06 vis-V03-00-07
810
81125th January 2001  John Allison  (opengl-V03-00-00)
812- Implemented running re-calculation of up-vector in the case of "object
813  rotation" (lights move with camera) to prevent "flipping" of view when
814  camera passes through up-vector.  Note that the default is "camera
815  rotation" (lights do not move with camera, i.e., remain fixed relative
816  to object) so the default is that this "flipping" can happen.  To set
817  "object rotation" (lights move with camera) use
818  /vis/lights/move_with_camera true (soon to be
819  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
820  on Rotation Panel in OpenGLXm mode.
821- Changed some objects to references for efficiency.  E.g.:
822  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
823
82422nd May 2000  John Allison  (opengl-V01-01-00)
825- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
826  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
827    static XVisualInfo* vi_single_buffer;
828    static XVisualInfo* vi_double_buffer;
829- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
830  G4OpenGLXViewer.
831- Protected double deletion of window in destructors of G4OpenGLXmViewer
832  and G4OpenGLXViewer (Guy Barrand).
833- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
834- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
835  constructors.
Note: See TracBrowser for help on using the repository browser.
