21- Better way to hold Meta Keys and shortcuts
22
2323th June 2010  Laurent Garnier
24- G4OpenGLImmediate/StoredQtViewer : Fix compilation warnings
25- G4OpenGLQtViewer : Add protection on Vis Tab without UI Qt
26
274th June 2010  Laurent Garnier (opengl-V09-03-07)
28- G4OpenGLImmediate/StoredQtViewer : Add protection against multiple
29  repaint call. Add protection against resizeGl with bad values
30
313rd June 2010  John Allison  (opengl-V09-03-06)
32- G4OpenGLImmediateSceneHandler: Re-instate
33  // Make sure screen corresponds to graphical database...
34  if (fpViewer) {
35    fpViewer -> SetView ();
36    fpViewer -> ClearView ();
37    fpViewer -> DrawView ();
38  }
39  I was wrong - it *is* necessary.  If not there, events are not refreshed.
40  So this and similar changes below are all back to geant4-09-03, including
41  glFlush, which is still a big performance penalty on Mac's Snow Leopard.
42
433rd June 2010  John Allison  (opengl-V09-03-05)
44- Restored following files to geant4-09-03 in interests of stable behaviour:
45  o G4OpenGLStoredSceneHandler.cc
46    Restored code removed in opengl-V09-03-03:
47  // Make sure screen corresponds to graphical database...
48  if (fpViewer) {
49    fpViewer -> SetView ();
50    fpViewer -> ClearView ();
51    fpViewer -> DrawView ();
52  }
53  o G4OpenGLStoredXViewer.cc:
54    Restore to geant4-09-03.  Restored code removed in opengl-V09-03-03:
55      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
56        DrawDisplayLists ();
57        FinishView ();
58- Note: G4OpenGLImmediateSceneHandler: Same code commented out.  I think
59  it's not necessary for immediate mode.
60
6130th May 2010  John Allison  (opengl-V09-03-04)
62- G4OpenGLSceneHandler: Added AddCompound(const G4VDigi&).
63
6429th May 2010  John Allison  (opengl-V09-03-03)
65- G4OpenGLImmediateSceneHandler.cc, G4OpenGLStoredSceneHandler.cc:
66  Removed the following from ClearTransientStrore (was causing
67  unnecessary drawing and flipping buffers?):
68  // Make sure screen corresponds to graphical database...
69  if (fpViewer) {
70    fpViewer -> SetView ();
71    fpViewer -> ClearView ();
72    fpViewer -> DrawView ();
73  }
74- G4OpenGLStoredXViewer.cc:
75  Commented out as follows in DrawView (was causing extra buffer swap,
76  thus showing bad picture; can't recall why it was introduced):
77      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
78        //DrawDisplayLists ();  ????????? (JA)
79        //FinishView ();        ????????? (JA)

4544th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
455- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
456  for OGL*Win32.  Still doesn't work for OGL*Xm.
457
4583rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
459- G4OpenGLStoredSceneHandler:
460  o Re-organised display lists on a per-primitive basis, i.e., one
461    display list per primitive.  (This is so that, except for text,
462    the colour - or, rather, intensity - can be brought out of the
463    display list into the TOList (Transient Object List) and
464    controlled for the Display-by-Time feature.  Previously, if more
465    than one primitive were drawn between BeginPrimitives and
466    EndPrimitives, it would finish up all in one display list, colour
467    commands included. Rationalises and fixes a rare bug in the
468    Display-by-Time feature - see August 2006.)
469  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
470    one primoitive to fit with the above re-organisation.
471- Implemented picking for OGLIX.
472
47325th March 2007  John Allison  (opengl-V08-02-03)
474- Fix compiler warnings.
475
4768th February 2007  John Allison  (opengl-V08-02-02)
477- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
478- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
479  .but not switched back.  Not serious, because context was always set
480  before normal drawing.)
481
4829th January 2007  John Allison  (opengl-V08-02-01)
483- Implemented bitmap markers for MarkerSizeType == screen.  (The old
484  polygon implementation remains for MarkerSizeType == world.)
485- Added G4OpenGLBitMapStore to assist the above.
486- G4OpenGLXViewer::CreateGLXContext:
487  o Bug fix: Added missing break in colormap lookup routine.
488
4895th January 2007  John Allison  (opengl-V08-02-00)
490- G4OpenGLSceneHandler.cc:
491  o Followed change of signature of GetLineWidth in visman-V08-02-00.
492  o Minor efficiency improvements.
493
49421st November 2006  John Allison  (opengl-V08-01-09)
495- Fixed compiler warnings.
496
4971st November 2006  John Allison  (opengl-V08-01-08)
498- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
499  actually initiates a print, rather than set a flag for printing.
500
50124th October 2006  John Allison  (opengl-V08-01-07)
502- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
503- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
504
50519th September 2006  John Allison  (opengl-V08-01-06)
506- Added time origin for light front.
507- Added /vis/ogl/set/transparency.
508- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
509
5104th September 2006  John Allison  (opengl-V08-01-05)
511- Implement cutaways.
512- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
513  primitives (see detector being drawn).
514- /vis/oglx/set/printEPS: change parameter default to true.
515
51630th August 2006  John Allison  (opengl-V08-01-04)
517- G4OpenGLSceneHandler:
518  o Implemented line width.
519  o Switched off back face culling when clipping so that the inside of
520    volumes can be seen.
521  o Added CreateSection/CutawayPolyhedron to exploit generic
522    sectioning (DCUT) and cutaways.  Currently not activated due to
523    instabilities in BooleanProcessor.  Local sectioning still active
524    but broken (at least on Mac) due to apparent change in effect of
525    clipping planes (polyhedron edges not reconstructed).
526  o Rationalised calculation of marker size.
527- G4OpenGLStoredSceneHandler:
528  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
529  o Pick up time range from G4VisAttributes.
530- G4OpenGLViewer(Messenger):
531  o Added position and colour to /vis/ogl/set/displayHeadTime.
532  o Added /vis/ogl/set/displayLightFront.
533- G4OpenGLStoredViewer.cc:
534  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
535  o Added position and colour to DisplayHeadTime.
536  o Added DisplayLightFront.
537 
53816th August 2006  John Allison  (opengl-V08-01-03)
539- Corrected Solaris compilation error.
540- Added /vis/ogl/set/fade and displayHeadTime.
541
54214th August 2006  John Allison  (opengl-V08-01-02)
543- Needs visman-V08-01-02.
544- G4OpenGLStored: Implemented display-by-time.  Only available in
545  stored mode at present.  Only implemented for circle, square,
546  polyline and polymarker at present, enough for currently available
547  trajectory models.  Time is communicated via G4AttValues.
548- Added G4OpenGLViewerMessenger.
549- Added /vis/ogl/set/startTime and endTime of displayed objects.
550- All factories: Instantiated G4OpenGLViewerMessenger.
551- G4OpenGLViewer: Added fStart/EndTime.
552- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
553  spewPrimitiveEPS and spewSortedFeedback.
554
55517th July  John Allison  (opengl-V08-01-01)
556- Added /vis/oglx/set/printEPS (prints eps file on every update).
557
5583rd July 2006  John Allison  (opengl-V08-01-00)
559- Elimination of redundant variable doublebuffer and implementation of
560  FinishView in all viewers.
561
56230th May 2006  Joseph Perl  (opengl-V08-00-08)
563- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
564  variable seems to have random behavior and should be assumed false for
565  this viewer.
566
56729th May 2006  Joseph Perl  (opengl-V08-00-07)
568- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
569  Removed common FinishView and instead made separate FinishView for the two different
570  versions of this viewer since each wants a different buffer swapping behaviour.
571
57212th May 2006  John Allison  (opengl-V08-00-06)
573- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
574
57528th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
576- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
577  recomputing transients.
578
57924th April 2006  John Allison  (opengl-V08-00-04)
580- Fixed compilation problem on Windows.
581
58219th April 2006  John Allison  (opengl-V08-00-03)
583- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
584  G4OpenGLImmediateSceneHandler:
585  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
586    greps-V08-00-02).
587  o Migrated to direct access to G4PhysicalVolumeModel.
588- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
589  of display lists in DrawView.
590
59114th March 2006  John Allison  (opengl-V08-00-02)
592- Refined display list building and re-drawing algorithm.
593  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
594  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
595- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
596  re-use algorithm.  In test19 with global culling off, numbers of
597  display lists used are:
598  o 191  No re-use:
599  o  73  Before this change: re-use except replicas (includes parameterised).
600  o  33  After this change: re-use except parameterised and replicas in radius.
601
60226th January 2006  John Allison  (opengl-V08-00-01)
603- Coworks with visman-V08-00-04 (removed fModified).
604- Removed references to fModified.
605- Tidying: Removed unnecessary ClearView.
606- G4OpenGLSceneHandler.cc: Added some (commented out) code for
607  possible future implementation of 2D drawing.
608- G4OpenGLXViewer.cc: Improved exception printing.
609
61011th January 2006  John Allison  (opengl-V08-00-00)
611- Improved efficiency: all DrawView's:
612  o Don't call ClearView.
613  o Set flag so SetView will not be called in ProcessView.
614  o Leave background colour to ClearView.
615- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
616- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
617  for current viewer.
618
61924th November 2005  John Allison  (opengl-V07-01-09)
620- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
621
62222nd November 2005  John Allison  (opengl-V07-01-08)
623- Added G4OpenGLXmViewerMessenger.
624- Corrected text position.
625- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
626
62717th November 2005  Gabriele Cosmo
628- Fixed settings of background style for WIN32 viewers.
629
63013th November 2005  John Allison  (opengl-V07-01-07)
631- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
632
63313th October 2005  John Allison  (opengl-V07-01-06)
634- Allowed any colour background.
635- Implemented non-uniform scaling.
636- Migration to <sstream>.
637
63829th September 2005  John Allison  (opengl-V07-01-05)
639- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
640  scene handler.
641- Re-implemented transparency button in OpenGLXm.
642
64313th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
644- Implemented white background for all OGL viewers.
645- G4OpenGLSceneHandler.cc:
646  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
647  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
648  o Corrected GetTextColour(text).
649  o Corrected GetColour(polyhedron).
650
6515th September 2005  John Allison  (opengl-V07-01-03)
652- Bug fix: stored transparent objects were being lost.
653
6542nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
655- Bug fix: edgeflags problem introduced with smooth shading in
656  opengl-V07-01-00.
657- Implementation of a "better algorithm" for the rendering of
658  transparent polyhedron objects.  It renders all opaque objects
659  first, then renders the transparent objects with the depth buffer in
660  read-only mode (see OpenGL Programming Guide).  It uses the new
661  facility in G4VSceneHandler::ProcessScene for an optional second pass
662  of the run-duration models in the scene.  Note this algorithm is
663  still only an approximation.  It will still give the wrong blended
664  colour if two transparent objects are rendered front first.  For
665  nested transparent objects, this is unfortunate, because
666  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
667  in such a way that mothers come first.  Also, there is no guaranteed
668  relationship between the order of rendering and the depth of two
669  transparent objects if they are at the same level or in different
670  branches of the hierarchy.  Still, the only error will be an
671  incorrect colour - the objects will still give the appearance of
672  transparency, so it's a pretty good algorithm.  (An even better
673  algorithm would be to attempt to render the facets in depth order,
674  deepest first.  But how do you calculate the depth - centre of area,
675  deepest corner?  One can still imagine pathalogical cases that would
676  sometimes give the wrong colour.  Also, for stored mode, the order
677  is fixed in a display list so when the user rotates the view, one
678  would lose the depth ordering.  I think we have to accept that
679  blending in OpenGL is only ever an approximation.  For accurate
680  blending, use RayTracer.)
681
68228th August 2005  John Allison  (opengl-V07-01-01)
683- Half-way implementation of rendering of transparent polyhedron
684  objects.  In this implementation, no account is taken of the order
685  of rendering.  Transparent objects are rendered with depth testing
686  off so that objects behind can still be seen.  But this means that
687  opaque objects in front do not obscure them - and they jolly well
688  should!  A better algorithm is to render all opaque objects first,
689  then render the transparent objects with the depth buffer in
690  read-only mode (see OpenGL Programming Guide).  This is going to
691  take a little more thought - see opengl-V07-01-02.
692
69320th July 2005  John Allison  (opengl-V07-01-00)
694- Introduced smooth shading, taking advantage of hitherto un-noticed
695  feature of HepPolyhedron::GetNextFacet that calculates the normals
696  at each vertex so that curved surfaces are rendered more
697  realistically (Gouraud shading).
698- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
699- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
700  the default window size.  It used to be 400x400, hardcoded in
701  G4OpenGLXmViewer.cc, but now it picks up the
702  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
703  The user may change it on the command line, e.g:
704    /vis/open OGLSXm 500
705  or
706    /vis/viewer/create ! ! 500
707
70830th May 2005  John Allison  (opengl-V07-00-03)
709- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
710  map of vectors in G4OpenGLFontBaseStore.)
711
7124th May 2005  John Allison  (opengl-V07-00-02)
713- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
714  was taken out to prevent recursive calling, but that seems to be OK,
715  and it is needed to implement refresh at end of event/run.)
716
71722nd April 2005  John Allison  (opengl-V07-00-01)
718- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
719  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
720  o In all concrete viewers, added call to CreateFontLists().
721  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
722  o There is no longer a need to implement in the XmViewer, since it
723    now inherits.  Thus the font code now only appears once for X.
724  o Awaiting implementation for WIN32.
725
72617th April 2005  John Allison  (opengl-V07-00-00)
727- Based on vis-V07-00-13.
728- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
729  creates display lists for nominated fonts.  Simple-minded scheme in
730  which each viewer creates its own font display lists for a variety
731  of sizes, which are accessed by the scene handler through a new
732  class, G4OpenGLFontBaseStore.  Affected methods:
733    G4OpenGLXViewer::CreateMainWindow()
734    G4OpenGLXmViewer::CreateMainWindow()
735    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
736
73718th November 2004  John Allison  (opengl-V06-02-07)
738- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
739
74015th November 2004  Guy Barrand
741- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
742  to see trajectories (for example with N03). Correct so that
743  ShowView do a FinishView that does : glFlush, wglSwapBuffer
744  and empty the Windows message queue.
745
74622nd September 2004  John Allison  (opengl-V06-02-06)
747- doxygen output to tmp area.
748- Trap non-regular polyhedrons.
749
75013th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
751- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
752  to allow for porting on CLHEP-1.9.X series.
753
75423rd July 2004  John Allison
755- Draws auxiliary edges if required.
756- Added auxiliary edge button.
757
75816th July 2004  John Allison  (opengl-V06-02-04)
759- Refinements to hidden line, hidden surface removal.
760
76114th July 2004  John Allison  (opengl-V06-02-03)
762- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
763
76413th July 2004  John Allison  (opengl-V06-02-02)
765- Hidden line *and* hidden surface removal now works.
766
7679th July 2004  John Allison  (opengl-V06-02-01)
768- Fixed long-standing problem with hidden line removal.
769- Improved messages on failure to get visual.
770- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
771  systems provided by default anyway, so no effect.
772
7731st July 2004  John Allison  (opengl-V06-02-00)
774- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
775- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
776
77718th June 2004  Gunter Folger (geant4-06-02)
7789th June 2004  Gabriele Cosmo  (vis-V06-01-03)
7797th June 2004  Gabriele Cosmo  (vis-V06-01-02)
780- GNUmakefile and disclaimer changes - see visualization/History.
781
7829th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
783- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
784
7857th April 2004  Guy Barrand
786- visualization/OpenGL/* : use the G4OpenGL.hh file.
787- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
788  the include of gl/gl.h and gl/glu.h that may be platform dependant.
789  It permits to rm some #ifdef WIN32 spread in the code. It opens also
790  the way to the usage of the Apple OpenGL on a Mac.
791
79217th February 2004  John Allison  (opengl-V06-00-00)
793- Fixed bug #581: wrong order of statements in
794  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
795
7964th October 2003  Gabriele Cosmo  (vis-V05-02-01)
797- GNUmakefile:
798  o replaced "digits+hits" with "digits_hits".
799- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
800
80122nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
802- Cosmetic change to regularise names:
803  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
804  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
805
80623rd June 2003  Guy Barrand  (opengl-V05-01-02)
807- Commit a first implementation of G4OpenGLWin32Viewer.
808
80910th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
810- More fixes for warnings in viewers classes.
811- Added inclusion of <windows.h> for WIN32 platforms when GL headers
812  are included.
813
81405th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
815- Fixes for porting compilation on WIN32:
816  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
817  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
818    since declared 'obsolete' in WIN32 platforms.
819
82027th November 2002  John Allison  (vis-V04-01-08)
821- Improved algorithm of CompareForKernelVisit.
822
82311th November 2002  John Allison  (opengl-V04-01-02)
824- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
825- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
826  call default but there as a marker and encourager.
827- Added tracking and digits+hits/hits to GNUmakefile.
828
82916th October 2002  John Allison  (opengl-V04-01-01)
830- Fix for WIN32.  Now compiles but viewer not implemented.
831
83224th June 2002  John Allison  (opengl-V04-01-00)
833- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
834
83510th June 2002  John Allison  (opengl-V04-00-03)
836- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
837
8386th June 2002  John Allison  (opengl-V04-00-02)
839- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
840
84123rd February 2002  John Allison  (opengl-V04-00-01)
842- Changes to encourage compilation on Windows in preparation for
843  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
844  glx.h, unistd.h and assert.h.
845
84624th August 2001  John Allison  (vis-V03-02-13)
847- Limited the printing of warnings in
848  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
849
85014th August 2001  John Allison  (vis-V03-02-11)
851- Improved KernelVisitDecision.
852- Fixed a few small bugs in multiple "stored" viewers, but see next item.
853- There's an outstanding bug in OpenGL Stored.  If there is more than
854  one viewer controlled by a scene handler, after a ClearStore on the
855  scene handler, e.g., with /vis/scene/notifyHandlers, the first
856  viewer to get refreshed should trigger the display list rebuild, but
857  the second need not.  However, when the second viewer's turn comes,
858  the display lists are there, and are called, e.g.,
859  G4OpenGLStoredXViewer::DrawView calls
860  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
861  nothing appears on the screen.  To overcome this there is some
862  temporary code in G4VViewer::NeedKernelVisit which marks *all*
863  viewers to force a rebuild.  To see the symptoms, comment out that
864  temporary code and issue these commands:
865    /vis/verbose c
866    /control/verbose 2

887  One of the viewers is empty.  Curious!!

8899th August 2001  John Allison  (vis-V03-02-10-00)
890- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
891- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
892  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
893  picked up by inheritance anyway.
894- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
895- Corrected order of calling base class functions in
896  G4OpenGLStoredSceneHandler::Begin/EndModeling.
897
89824th July 2001  John Allison  (vis-V03-02-06)
899- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.

90114th July 2001  John Allison (opengl-V03-02-00)
902- Fixed crash in optimised mode: added Initialise() to viewers so
903  that windows are opened after viewers are fully constructed.
904
9052nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
906- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
907
9087th March 2001  John Allison
909- Changed char* to const char* in many places and that gave problems in
910  calls to Xt and Xm.  Hope all's OK.  Differences:

91325th January 2001  John Allison  (opengl-V03-00-00)
914- Implemented running re-calculation of up-vector in the case of "object
915  rotation" (lights move with camera) to prevent "flipping" of view when
916  camera passes through up-vector.  Note that the default is "camera
917  rotation" (lights do not move with camera, i.e., remain fixed relative
918  to object) so the default is that this "flipping" can happen.  To set
919  "object rotation" (lights move with camera) use
920  /vis/lights/move_with_camera true (soon to be
921  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
922  on Rotation Panel in OpenGLXm mode.
923- Changed some objects to references for efficiency.  E.g.:
924  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
925
92622nd May 2000  John Allison  (opengl-V01-01-00)
927- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
928  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
929    static XVisualInfo* vi_single_buffer;
930    static XVisualInfo* vi_double_buffer;
931- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
932  G4OpenGLXViewer.
933- Protected double deletion of window in destructors of G4OpenGLXmViewer
934  and G4OpenGLXViewer (Guy Barrand).
935- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
936- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
937  constructors.
