291  o Correct path /vis/ogl/set/printMode.
292  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
293    and "/vis/ogl/printEPS").
294
2958th May 2007  John Allison  (opengl-V08-02-06)
296- Moved vectored PostScript printing to G4OpenGLViewer.
297- /vis/ogl/printEPS should work for all viewers, including Win32.
298- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
299  effective on X windows (and still somewhat buggy).
300
3014th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
302- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
303  for OGL*Win32.  Still doesn't work for OGL*Xm.
304
3053rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
306- G4OpenGLStoredSceneHandler:
307  o Re-organised display lists on a per-primitive basis, i.e., one
308    display list per primitive.  (This is so that, except for text,
309    the colour - or, rather, intensity - can be brought out of the
310    display list into the TOList (Transient Object List) and
311    controlled for the Display-by-Time feature.  Previously, if more
312    than one primitive were drawn between BeginPrimitives and
313    EndPrimitives, it would finish up all in one display list, colour
314    commands included. Rationalises and fixes a rare bug in the
315    Display-by-Time feature - see August 2006.)
316  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
317    one primoitive to fit with the above re-organisation.
318- Implemented picking for OGLIX.
319
32025th March 2007  John Allison  (opengl-V08-02-03)
321- Fix compiler warnings.
322
3238th February 2007  John Allison  (opengl-V08-02-02)
324- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
325- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
326  .but not switched back.  Not serious, because context was always set
327  before normal drawing.)
328
3299th January 2007  John Allison  (opengl-V08-02-01)
330- Implemented bitmap markers for MarkerSizeType == screen.  (The old
331  polygon implementation remains for MarkerSizeType == world.)
332- Added G4OpenGLBitMapStore to assist the above.
333- G4OpenGLXViewer::CreateGLXContext:
334  o Bug fix: Added missing break in colormap lookup routine.
335
3365th January 2007  John Allison  (opengl-V08-02-00)
337- G4OpenGLSceneHandler.cc:
338  o Followed change of signature of GetLineWidth in visman-V08-02-00.
339  o Minor efficiency improvements.
340
34121st November 2006  John Allison  (opengl-V08-01-09)
342- Fixed compiler warnings.
343
3441st November 2006  John Allison  (opengl-V08-01-08)
345- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
346  actually initiates a print, rather than set a flag for printing.
347
34824th October 2006  John Allison  (opengl-V08-01-07)
349- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

351
35219th September 2006  John Allison  (opengl-V08-01-06)
353- Added time origin for light front.
354- Added /vis/ogl/set/transparency.
355- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
356
3574th September 2006  John Allison  (opengl-V08-01-05)
358- Implement cutaways.
359- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
360  primitives (see detector being drawn).
361- /vis/oglx/set/printEPS: change parameter default to true.
362
36330th August 2006  John Allison  (opengl-V08-01-04)
364- G4OpenGLSceneHandler:
365  o Implemented line width.
366  o Switched off back face culling when clipping so that the inside of
367    volumes can be seen.
368  o Added CreateSection/CutawayPolyhedron to exploit generic
369    sectioning (DCUT) and cutaways.  Currently not activated due to
370    instabilities in BooleanProcessor.  Local sectioning still active
371    but broken (at least on Mac) due to apparent change in effect of
372    clipping planes (polyhedron edges not reconstructed).
373  o Rationalised calculation of marker size.
374- G4OpenGLStoredSceneHandler:
375  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
376  o Pick up time range from G4VisAttributes.
377- G4OpenGLViewer(Messenger):
378  o Added position and colour to /vis/ogl/set/displayHeadTime.
379  o Added /vis/ogl/set/displayLightFront.
380- G4OpenGLStoredViewer.cc:
381  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
382  o Added position and colour to DisplayHeadTime.
383  o Added DisplayLightFront.
384 
38516th August 2006  John Allison  (opengl-V08-01-03)
386- Corrected Solaris compilation error.
387- Added /vis/ogl/set/fade and displayHeadTime.
388
38914th August 2006  John Allison  (opengl-V08-01-02)
390- Needs visman-V08-01-02.
391- G4OpenGLStored: Implemented display-by-time.  Only available in
392  stored mode at present.  Only implemented for circle, square,
393  polyline and polymarker at present, enough for currently available
394  trajectory models.  Time is communicated via G4AttValues.
395- Added G4OpenGLViewerMessenger.
396- Added /vis/ogl/set/startTime and endTime of displayed objects.
397- All factories: Instantiated G4OpenGLViewerMessenger.
398- G4OpenGLViewer: Added fStart/EndTime.
399- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
400  spewPrimitiveEPS and spewSortedFeedback.
401
40217th July  John Allison  (opengl-V08-01-01)
403- Added /vis/oglx/set/printEPS (prints eps file on every update).
404
4053rd July 2006  John Allison  (opengl-V08-01-00)
406- Elimination of redundant variable doublebuffer and implementation of
407  FinishView in all viewers.
408
40930th May 2006  Joseph Perl  (opengl-V08-00-08)
410- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
411  variable seems to have random behavior and should be assumed false for
412  this viewer.
413
41429th May 2006  Joseph Perl  (opengl-V08-00-07)
415- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
416  Removed common FinishView and instead made separate FinishView for the two different
417  versions of this viewer since each wants a different buffer swapping behaviour.
418
41912th May 2006  John Allison  (opengl-V08-00-06)
420- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
421
42228th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
423- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
424  recomputing transients.

431  G4OpenGLImmediateSceneHandler:
432  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
433    greps-V08-00-02).
434  o Migrated to direct access to G4PhysicalVolumeModel.
435- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
436  of display lists in DrawView.
437
43814th March 2006  John Allison  (opengl-V08-00-02)
439- Refined display list building and re-drawing algorithm.
440  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
441  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
442- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
443  re-use algorithm.  In test19 with global culling off, numbers of
444  display lists used are:
445  o 191  No re-use:
446  o  73  Before this change: re-use except replicas (includes parameterised).
447  o  33  After this change: re-use except parameterised and replicas in radius.
448
44926th January 2006  John Allison  (opengl-V08-00-01)
450- Coworks with visman-V08-00-04 (removed fModified).
451- Removed references to fModified.
452- Tidying: Removed unnecessary ClearView.
453- G4OpenGLSceneHandler.cc: Added some (commented out) code for
454  possible future implementation of 2D drawing.
455- G4OpenGLXViewer.cc: Improved exception printing.
456
45711th January 2006  John Allison  (opengl-V08-00-00)
458- Improved efficiency: all DrawView's:
459  o Don't call ClearView.
460  o Set flag so SetView will not be called in ProcessView.
461  o Leave background colour to ClearView.
462- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
463- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
464  for current viewer.
465
46624th November 2005  John Allison  (opengl-V07-01-09)
467- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
468
46922nd November 2005  John Allison  (opengl-V07-01-08)
470- Added G4OpenGLXmViewerMessenger.
471- Corrected text position.
472- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
473
47417th November 2005  Gabriele Cosmo
475- Fixed settings of background style for WIN32 viewers.
476
47713th November 2005  John Allison  (opengl-V07-01-07)
478- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
479
48013th October 2005  John Allison  (opengl-V07-01-06)
481- Allowed any colour background.
482- Implemented non-uniform scaling.
483- Migration to <sstream>.
484
48529th September 2005  John Allison  (opengl-V07-01-05)
486- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
487  scene handler.
488- Re-implemented transparency button in OpenGLXm.
489
49013th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
491- Implemented white background for all OGL viewers.
492- G4OpenGLSceneHandler.cc:
493  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
494  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
495  o Corrected GetTextColour(text).
496  o Corrected GetColour(polyhedron).
497
4985th September 2005  John Allison  (opengl-V07-01-03)
499- Bug fix: stored transparent objects were being lost.
500
5012nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
502- Bug fix: edgeflags problem introduced with smooth shading in
503  opengl-V07-01-00.
504- Implementation of a "better algorithm" for the rendering of
505  transparent polyhedron objects.  It renders all opaque objects
506  first, then renders the transparent objects with the depth buffer in
507  read-only mode (see OpenGL Programming Guide).  It uses the new
508  facility in G4VSceneHandler::ProcessScene for an optional second pass
509  of the run-duration models in the scene.  Note this algorithm is
510  still only an approximation.  It will still give the wrong blended
511  colour if two transparent objects are rendered front first.  For
512  nested transparent objects, this is unfortunate, because
513  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
514  in such a way that mothers come first.  Also, there is no guaranteed
515  relationship between the order of rendering and the depth of two
516  transparent objects if they are at the same level or in different
517  branches of the hierarchy.  Still, the only error will be an
518  incorrect colour - the objects will still give the appearance of
519  transparency, so it's a pretty good algorithm.  (An even better
520  algorithm would be to attempt to render the facets in depth order,
521  deepest first.  But how do you calculate the depth - centre of area,
522  deepest corner?  One can still imagine pathalogical cases that would
523  sometimes give the wrong colour.  Also, for stored mode, the order
524  is fixed in a display list so when the user rotates the view, one
525  would lose the depth ordering.  I think we have to accept that
526  blending in OpenGL is only ever an approximation.  For accurate
527  blending, use RayTracer.)
528
52928th August 2005  John Allison  (opengl-V07-01-01)
530- Half-way implementation of rendering of transparent polyhedron
531  objects.  In this implementation, no account is taken of the order
532  of rendering.  Transparent objects are rendered with depth testing
533  off so that objects behind can still be seen.  But this means that
534  opaque objects in front do not obscure them - and they jolly well
535  should!  A better algorithm is to render all opaque objects first,
536  then render the transparent objects with the depth buffer in
537  read-only mode (see OpenGL Programming Guide).  This is going to
538  take a little more thought - see opengl-V07-01-02.
539
54020th July 2005  John Allison  (opengl-V07-01-00)
541- Introduced smooth shading, taking advantage of hitherto un-noticed
542  feature of HepPolyhedron::GetNextFacet that calculates the normals
543  at each vertex so that curved surfaces are rendered more
544  realistically (Gouraud shading).
545- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
546- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
547  the default window size.  It used to be 400x400, hardcoded in
548  G4OpenGLXmViewer.cc, but now it picks up the
549  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
550  The user may change it on the command line, e.g:
551    /vis/open OGLSXm 500
552  or
553    /vis/viewer/create ! ! 500
554
55530th May 2005  John Allison  (opengl-V07-00-03)
556- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
557  map of vectors in G4OpenGLFontBaseStore.)
558
5594th May 2005  John Allison  (opengl-V07-00-02)
560- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
561  was taken out to prevent recursive calling, but that seems to be OK,
562  and it is needed to implement refresh at end of event/run.)
563
56422nd April 2005  John Allison  (opengl-V07-00-01)
565- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
566  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
567  o In all concrete viewers, added call to CreateFontLists().
568  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
569  o There is no longer a need to implement in the XmViewer, since it
570    now inherits.  Thus the font code now only appears once for X.
571  o Awaiting implementation for WIN32.
572
57317th April 2005  John Allison  (opengl-V07-00-00)
574- Based on vis-V07-00-13.
575- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
576  creates display lists for nominated fonts.  Simple-minded scheme in
577  which each viewer creates its own font display lists for a variety
578  of sizes, which are accessed by the scene handler through a new
579  class, G4OpenGLFontBaseStore.  Affected methods:
580    G4OpenGLXViewer::CreateMainWindow()
581    G4OpenGLXmViewer::CreateMainWindow()
582    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
583
58418th November 2004  John Allison  (opengl-V06-02-07)
585- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
586
58715th November 2004  Guy Barrand
588- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
589  to see trajectories (for example with N03). Correct so that
590  ShowView do a FinishView that does : glFlush, wglSwapBuffer
591  and empty the Windows message queue.
592
59322nd September 2004  John Allison  (opengl-V06-02-06)
594- doxygen output to tmp area.
595- Trap non-regular polyhedrons.
596
59713th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
598- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
599  to allow for porting on CLHEP-1.9.X series.
600
60123rd July 2004  John Allison
602- Draws auxiliary edges if required.
603- Added auxiliary edge button.
604
60516th July 2004  John Allison  (opengl-V06-02-04)
606- Refinements to hidden line, hidden surface removal.
607
60814th July 2004  John Allison  (opengl-V06-02-03)
609- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
610
61113th July 2004  John Allison  (opengl-V06-02-02)
612- Hidden line *and* hidden surface removal now works.
613
6149th July 2004  John Allison  (opengl-V06-02-01)
615- Fixed long-standing problem with hidden line removal.
616- Improved messages on failure to get visual.
617- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
618  systems provided by default anyway, so no effect.
619
6201st July 2004  John Allison  (opengl-V06-02-00)
621- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
622- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
623
62418th June 2004  Gunter Folger (geant4-06-02)
6259th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6267th June 2004  Gabriele Cosmo  (vis-V06-01-02)
627- GNUmakefile and disclaimer changes - see visualization/History.
628
6299th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
630- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
631
6327th April 2004  Guy Barrand
633- visualization/OpenGL/* : use the G4OpenGL.hh file.
634- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
635  the include of gl/gl.h and gl/glu.h that may be platform dependant.
636  It permits to rm some #ifdef WIN32 spread in the code. It opens also
637  the way to the usage of the Apple OpenGL on a Mac.
638
63917th February 2004  John Allison  (opengl-V06-00-00)
640- Fixed bug #581: wrong order of statements in
641  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
642
6434th October 2003  Gabriele Cosmo  (vis-V05-02-01)
644- GNUmakefile:
645  o replaced "digits+hits" with "digits_hits".
646- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
647
64822nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
649- Cosmetic change to regularise names:
650  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
651  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
652
65323rd June 2003  Guy Barrand  (opengl-V05-01-02)
654- Commit a first implementation of G4OpenGLWin32Viewer.
655
65610th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
657- More fixes for warnings in viewers classes.
658- Added inclusion of <windows.h> for WIN32 platforms when GL headers
659  are included.
660
66105th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
662- Fixes for porting compilation on WIN32:
663  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
664  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
665    since declared 'obsolete' in WIN32 platforms.
666
66727th November 2002  John Allison  (vis-V04-01-08)
668- Improved algorithm of CompareForKernelVisit.
669
67011th November 2002  John Allison  (opengl-V04-01-02)
671- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
672- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
673  call default but there as a marker and encourager.
674- Added tracking and digits+hits/hits to GNUmakefile.
675
67616th October 2002  John Allison  (opengl-V04-01-01)
677- Fix for WIN32.  Now compiles but viewer not implemented.
678
67924th June 2002  John Allison  (opengl-V04-01-00)
680- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
681
68210th June 2002  John Allison  (opengl-V04-00-03)
683- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
684
6856th June 2002  John Allison  (opengl-V04-00-02)
686- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
687
68823rd February 2002  John Allison  (opengl-V04-00-01)
689- Changes to encourage compilation on Windows in preparation for
690  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
691  glx.h, unistd.h and assert.h.
692
69324th August 2001  John Allison  (vis-V03-02-13)
694- Limited the printing of warnings in
695  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
696
69714th August 2001  John Allison  (vis-V03-02-11)
698- Improved KernelVisitDecision.
699- Fixed a few small bugs in multiple "stored" viewers, but see next item.
700- There's an outstanding bug in OpenGL Stored.  If there is more than
701  one viewer controlled by a scene handler, after a ClearStore on the
702  scene handler, e.g., with /vis/scene/notifyHandlers, the first
703  viewer to get refreshed should trigger the display list rebuild, but
704  the second need not.  However, when the second viewer's turn comes,
705  the display lists are there, and are called, e.g.,
706  G4OpenGLStoredXViewer::DrawView calls
707  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
708  nothing appears on the screen.  To overcome this there is some
709  temporary code in G4VViewer::NeedKernelVisit which marks *all*
710  viewers to force a rebuild.  To see the symptoms, comment out that
711  temporary code and issue these commands:
712    /vis/verbose c
713    /control/verbose 2
714    /vis/scene/create
715    /vis/scene/add/volume
716    /vis/sceneHandler/create OGLSX
717    /vis/viewer/create ! ! 1
718    /run/beamOn
719    /vis/viewer/create ! ! 1
720    /vis/viewer/select viewer-0
721    /vis/viewer/viewpointThetaPhi 20 20
722    /vis/viewer/select viewer-1
723    /vis/viewer/viewpointThetaPhi 40 40
724    /vis/viewer/set/style surface
725    /vis/viewer/refresh
726    /vis/viewer/select viewer-0
727    /vis/viewer/refresh
728    /vis/viewer/select viewer-1
729    /vis/viewer/set/style wireframe
730    /vis/scene/notifyHandlers
731  You may have to do this too:
732    /vis/viewer/select viewer-0
733    /vis/scene/notifyHandlers
734  One of the viewers is empty.  Curious!!
735
7369th August 2001  John Allison  (vis-V03-02-10-00)
737- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
738- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
739  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
740  picked up by inheritance anyway.
741- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
742- Corrected order of calling base class functions in
743  G4OpenGLStoredSceneHandler::Begin/EndModeling.
744
74524th July 2001  John Allison  (vis-V03-02-06)
746- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
747
74814th July 2001  John Allison (opengl-V03-02-00)
749- Fixed crash in optimised mode: added Initialise() to viewers so
750  that windows are opened after viewers are fully constructed.
751
7522nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
753- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
754
7557th March 2001  John Allison
756- Changed char* to const char* in many places and that gave problems in
757  calls to Xt and Xm.  Hope all's OK.  Differences:
758    cvs diff -r vis-V03-00-06 vis-V03-00-07
759
76025th January 2001  John Allison  (opengl-V03-00-00)
761- Implemented running re-calculation of up-vector in the case of "object
762  rotation" (lights move with camera) to prevent "flipping" of view when
763  camera passes through up-vector.  Note that the default is "camera
764  rotation" (lights do not move with camera, i.e., remain fixed relative
765  to object) so the default is that this "flipping" can happen.  To set
766  "object rotation" (lights move with camera) use
767  /vis/lights/move_with_camera true (soon to be
768  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
769  on Rotation Panel in OpenGLXm mode.
770- Changed some objects to references for efficiency.  E.g.:
771  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
772
77322nd May 2000  John Allison  (opengl-V01-01-00)
774- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
775  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
776    static XVisualInfo* vi_single_buffer;
777    static XVisualInfo* vi_double_buffer;
778- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
779  G4OpenGLXViewer.
780- Protected double deletion of window in destructors of G4OpenGLXmViewer
781  and G4OpenGLXViewer (Guy Barrand).
782- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
783- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
784  constructors.
Note: See TracBrowser for help on using the repository browser.
