289    and "/vis/ogl/printEPS").
290
2918th May 2007  John Allison  (opengl-V08-02-06)
292- Moved vectored PostScript printing to G4OpenGLViewer.
293- /vis/ogl/printEPS should work for all viewers, including Win32.
294- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
295  effective on X windows (and still somewhat buggy).
296
2974th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
298- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
299  for OGL*Win32.  Still doesn't work for OGL*Xm.
300
3013rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
302- G4OpenGLStoredSceneHandler:
303  o Re-organised display lists on a per-primitive basis, i.e., one
304    display list per primitive.  (This is so that, except for text,
305    the colour - or, rather, intensity - can be brought out of the
306    display list into the TOList (Transient Object List) and
307    controlled for the Display-by-Time feature.  Previously, if more
308    than one primitive were drawn between BeginPrimitives and
309    EndPrimitives, it would finish up all in one display list, colour
310    commands included. Rationalises and fixes a rare bug in the
311    Display-by-Time feature - see August 2006.)
312  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
313    one primoitive to fit with the above re-organisation.
314- Implemented picking for OGLIX.
315
31625th March 2007  John Allison  (opengl-V08-02-03)
317- Fix compiler warnings.
318
3198th February 2007  John Allison  (opengl-V08-02-02)
320- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
321- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
322  .but not switched back.  Not serious, because context was always set
323  before normal drawing.)
324
3259th January 2007  John Allison  (opengl-V08-02-01)
326- Implemented bitmap markers for MarkerSizeType == screen.  (The old
327  polygon implementation remains for MarkerSizeType == world.)
328- Added G4OpenGLBitMapStore to assist the above.
329- G4OpenGLXViewer::CreateGLXContext:
330  o Bug fix: Added missing break in colormap lookup routine.
331
3325th January 2007  John Allison  (opengl-V08-02-00)
333- G4OpenGLSceneHandler.cc:
334  o Followed change of signature of GetLineWidth in visman-V08-02-00.
335  o Minor efficiency improvements.
336
33721st November 2006  John Allison  (opengl-V08-01-09)
338- Fixed compiler warnings.
339
3401st November 2006  John Allison  (opengl-V08-01-08)
341- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
342  actually initiates a print, rather than set a flag for printing.
343
34424th October 2006  John Allison  (opengl-V08-01-07)
345- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
346- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
347
34819th September 2006  John Allison  (opengl-V08-01-06)
349- Added time origin for light front.
350- Added /vis/ogl/set/transparency.
351- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
352
3534th September 2006  John Allison  (opengl-V08-01-05)
354- Implement cutaways.
355- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
356  primitives (see detector being drawn).
357- /vis/oglx/set/printEPS: change parameter default to true.
358
35930th August 2006  John Allison  (opengl-V08-01-04)
360- G4OpenGLSceneHandler:
361  o Implemented line width.
362  o Switched off back face culling when clipping so that the inside of
363    volumes can be seen.
364  o Added CreateSection/CutawayPolyhedron to exploit generic
365    sectioning (DCUT) and cutaways.  Currently not activated due to
366    instabilities in BooleanProcessor.  Local sectioning still active
367    but broken (at least on Mac) due to apparent change in effect of
368    clipping planes (polyhedron edges not reconstructed).
369  o Rationalised calculation of marker size.
370- G4OpenGLStoredSceneHandler:
371  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
372  o Pick up time range from G4VisAttributes.
373- G4OpenGLViewer(Messenger):
374  o Added position and colour to /vis/ogl/set/displayHeadTime.
375  o Added /vis/ogl/set/displayLightFront.
376- G4OpenGLStoredViewer.cc:
377  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
378  o Added position and colour to DisplayHeadTime.
379  o Added DisplayLightFront.
380 
38116th August 2006  John Allison  (opengl-V08-01-03)
382- Corrected Solaris compilation error.
383- Added /vis/ogl/set/fade and displayHeadTime.
384
38514th August 2006  John Allison  (opengl-V08-01-02)
386- Needs visman-V08-01-02.
387- G4OpenGLStored: Implemented display-by-time.  Only available in
388  stored mode at present.  Only implemented for circle, square,
389  polyline and polymarker at present, enough for currently available
390  trajectory models.  Time is communicated via G4AttValues.
391- Added G4OpenGLViewerMessenger.
392- Added /vis/ogl/set/startTime and endTime of displayed objects.
393- All factories: Instantiated G4OpenGLViewerMessenger.
394- G4OpenGLViewer: Added fStart/EndTime.
395- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
396  spewPrimitiveEPS and spewSortedFeedback.
397
39817th July  John Allison  (opengl-V08-01-01)
399- Added /vis/oglx/set/printEPS (prints eps file on every update).
400
4013rd July 2006  John Allison  (opengl-V08-01-00)
402- Elimination of redundant variable doublebuffer and implementation of
403  FinishView in all viewers.
404
40530th May 2006  Joseph Perl  (opengl-V08-00-08)
406- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
407  variable seems to have random behavior and should be assumed false for
408  this viewer.
409
41029th May 2006  Joseph Perl  (opengl-V08-00-07)
411- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
412  Removed common FinishView and instead made separate FinishView for the two different
413  versions of this viewer since each wants a different buffer swapping behaviour.
414
41512th May 2006  John Allison  (opengl-V08-00-06)
416- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
417
41828th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
419- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
420  recomputing transients.

429    greps-V08-00-02).
430  o Migrated to direct access to G4PhysicalVolumeModel.
431- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
432  of display lists in DrawView.
433
43414th March 2006  John Allison  (opengl-V08-00-02)
435- Refined display list building and re-drawing algorithm.
436  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
437  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
438- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
439  re-use algorithm.  In test19 with global culling off, numbers of
440  display lists used are:
441  o 191  No re-use:
442  o  73  Before this change: re-use except replicas (includes parameterised).
443  o  33  After this change: re-use except parameterised and replicas in radius.
444
44526th January 2006  John Allison  (opengl-V08-00-01)
446- Coworks with visman-V08-00-04 (removed fModified).
447- Removed references to fModified.
448- Tidying: Removed unnecessary ClearView.
449- G4OpenGLSceneHandler.cc: Added some (commented out) code for
450  possible future implementation of 2D drawing.
451- G4OpenGLXViewer.cc: Improved exception printing.
452
45311th January 2006  John Allison  (opengl-V08-00-00)
454- Improved efficiency: all DrawView's:
455  o Don't call ClearView.
456  o Set flag so SetView will not be called in ProcessView.
457  o Leave background colour to ClearView.
458- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
459- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
460  for current viewer.
461
46224th November 2005  John Allison  (opengl-V07-01-09)
463- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
464
46522nd November 2005  John Allison  (opengl-V07-01-08)
466- Added G4OpenGLXmViewerMessenger.
467- Corrected text position.
468- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
469
47017th November 2005  Gabriele Cosmo
471- Fixed settings of background style for WIN32 viewers.
472
47313th November 2005  John Allison  (opengl-V07-01-07)
474- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
475
47613th October 2005  John Allison  (opengl-V07-01-06)
477- Allowed any colour background.
478- Implemented non-uniform scaling.
479- Migration to <sstream>.
480
48129th September 2005  John Allison  (opengl-V07-01-05)
482- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
483  scene handler.
484- Re-implemented transparency button in OpenGLXm.
485
48613th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
487- Implemented white background for all OGL viewers.
488- G4OpenGLSceneHandler.cc:
489  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
490  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
491  o Corrected GetTextColour(text).
492  o Corrected GetColour(polyhedron).
493
4945th September 2005  John Allison  (opengl-V07-01-03)
495- Bug fix: stored transparent objects were being lost.
496
4972nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
498- Bug fix: edgeflags problem introduced with smooth shading in
499  opengl-V07-01-00.
500- Implementation of a "better algorithm" for the rendering of
501  transparent polyhedron objects.  It renders all opaque objects
502  first, then renders the transparent objects with the depth buffer in
503  read-only mode (see OpenGL Programming Guide).  It uses the new
504  facility in G4VSceneHandler::ProcessScene for an optional second pass
505  of the run-duration models in the scene.  Note this algorithm is
506  still only an approximation.  It will still give the wrong blended
507  colour if two transparent objects are rendered front first.  For
508  nested transparent objects, this is unfortunate, because
509  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
510  in such a way that mothers come first.  Also, there is no guaranteed
511  relationship between the order of rendering and the depth of two
512  transparent objects if they are at the same level or in different
513  branches of the hierarchy.  Still, the only error will be an
514  incorrect colour - the objects will still give the appearance of
515  transparency, so it's a pretty good algorithm.  (An even better
516  algorithm would be to attempt to render the facets in depth order,
517  deepest first.  But how do you calculate the depth - centre of area,
518  deepest corner?  One can still imagine pathalogical cases that would
519  sometimes give the wrong colour.  Also, for stored mode, the order
520  is fixed in a display list so when the user rotates the view, one
521  would lose the depth ordering.  I think we have to accept that
522  blending in OpenGL is only ever an approximation.  For accurate
523  blending, use RayTracer.)
524
52528th August 2005  John Allison  (opengl-V07-01-01)
526- Half-way implementation of rendering of transparent polyhedron
527  objects.  In this implementation, no account is taken of the order
528  of rendering.  Transparent objects are rendered with depth testing
529  off so that objects behind can still be seen.  But this means that
530  opaque objects in front do not obscure them - and they jolly well
531  should!  A better algorithm is to render all opaque objects first,
532  then render the transparent objects with the depth buffer in
533  read-only mode (see OpenGL Programming Guide).  This is going to
534  take a little more thought - see opengl-V07-01-02.
535
53620th July 2005  John Allison  (opengl-V07-01-00)
537- Introduced smooth shading, taking advantage of hitherto un-noticed
538  feature of HepPolyhedron::GetNextFacet that calculates the normals
539  at each vertex so that curved surfaces are rendered more
540  realistically (Gouraud shading).
541- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
542- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
543  the default window size.  It used to be 400x400, hardcoded in
544  G4OpenGLXmViewer.cc, but now it picks up the
545  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
546  The user may change it on the command line, e.g:
547    /vis/open OGLSXm 500
548  or
549    /vis/viewer/create ! ! 500
550
55130th May 2005  John Allison  (opengl-V07-00-03)
552- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
553  map of vectors in G4OpenGLFontBaseStore.)
554
5554th May 2005  John Allison  (opengl-V07-00-02)
556- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
557  was taken out to prevent recursive calling, but that seems to be OK,
558  and it is needed to implement refresh at end of event/run.)
559
56022nd April 2005  John Allison  (opengl-V07-00-01)
561- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
562  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
563  o In all concrete viewers, added call to CreateFontLists().
564  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
565  o There is no longer a need to implement in the XmViewer, since it
566    now inherits.  Thus the font code now only appears once for X.
567  o Awaiting implementation for WIN32.
568
56917th April 2005  John Allison  (opengl-V07-00-00)
570- Based on vis-V07-00-13.
571- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
572  creates display lists for nominated fonts.  Simple-minded scheme in
573  which each viewer creates its own font display lists for a variety
574  of sizes, which are accessed by the scene handler through a new
575  class, G4OpenGLFontBaseStore.  Affected methods:
576    G4OpenGLXViewer::CreateMainWindow()
577    G4OpenGLXmViewer::CreateMainWindow()
578    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
579
58018th November 2004  John Allison  (opengl-V06-02-07)
581- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
582
58315th November 2004  Guy Barrand
584- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
585  to see trajectories (for example with N03). Correct so that
586  ShowView do a FinishView that does : glFlush, wglSwapBuffer
587  and empty the Windows message queue.
588
58922nd September 2004  John Allison  (opengl-V06-02-06)
590- doxygen output to tmp area.
591- Trap non-regular polyhedrons.
592
59313th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
594- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
595  to allow for porting on CLHEP-1.9.X series.
596
59723rd July 2004  John Allison
598- Draws auxiliary edges if required.
599- Added auxiliary edge button.
600
60116th July 2004  John Allison  (opengl-V06-02-04)
602- Refinements to hidden line, hidden surface removal.
603
60414th July 2004  John Allison  (opengl-V06-02-03)
605- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
606
60713th July 2004  John Allison  (opengl-V06-02-02)
608- Hidden line *and* hidden surface removal now works.
609
6109th July 2004  John Allison  (opengl-V06-02-01)
611- Fixed long-standing problem with hidden line removal.
612- Improved messages on failure to get visual.
613- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
614  systems provided by default anyway, so no effect.
615
6161st July 2004  John Allison  (opengl-V06-02-00)
617- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
618- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
619
62018th June 2004  Gunter Folger (geant4-06-02)
6219th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6227th June 2004  Gabriele Cosmo  (vis-V06-01-02)
623- GNUmakefile and disclaimer changes - see visualization/History.
624
6259th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
626- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
627
6287th April 2004  Guy Barrand
629- visualization/OpenGL/* : use the G4OpenGL.hh file.
630- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
631  the include of gl/gl.h and gl/glu.h that may be platform dependant.
632  It permits to rm some #ifdef WIN32 spread in the code. It opens also
633  the way to the usage of the Apple OpenGL on a Mac.
634
63517th February 2004  John Allison  (opengl-V06-00-00)
636- Fixed bug #581: wrong order of statements in
637  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
638
6394th October 2003  Gabriele Cosmo  (vis-V05-02-01)
640- GNUmakefile:
641  o replaced "digits+hits" with "digits_hits".
642- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
643
64422nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
645- Cosmetic change to regularise names:
646  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
647  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
648
64923rd June 2003  Guy Barrand  (opengl-V05-01-02)
650- Commit a first implementation of G4OpenGLWin32Viewer.
651
65210th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
653- More fixes for warnings in viewers classes.
654- Added inclusion of <windows.h> for WIN32 platforms when GL headers
655  are included.
656
65705th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
658- Fixes for porting compilation on WIN32:
659  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
660  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
661    since declared 'obsolete' in WIN32 platforms.
662
66327th November 2002  John Allison  (vis-V04-01-08)
664- Improved algorithm of CompareForKernelVisit.
665
66611th November 2002  John Allison  (opengl-V04-01-02)
667- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
668- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
669  call default but there as a marker and encourager.
670- Added tracking and digits+hits/hits to GNUmakefile.
671
67216th October 2002  John Allison  (opengl-V04-01-01)
673- Fix for WIN32.  Now compiles but viewer not implemented.
674
67524th June 2002  John Allison  (opengl-V04-01-00)
676- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
677
67810th June 2002  John Allison  (opengl-V04-00-03)
679- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
680
6816th June 2002  John Allison  (opengl-V04-00-02)
682- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
683
68423rd February 2002  John Allison  (opengl-V04-00-01)
685- Changes to encourage compilation on Windows in preparation for
686  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
687  glx.h, unistd.h and assert.h.
688
68924th August 2001  John Allison  (vis-V03-02-13)
690- Limited the printing of warnings in
691  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
692
69314th August 2001  John Allison  (vis-V03-02-11)
694- Improved KernelVisitDecision.
695- Fixed a few small bugs in multiple "stored" viewers, but see next item.
696- There's an outstanding bug in OpenGL Stored.  If there is more than
697  one viewer controlled by a scene handler, after a ClearStore on the
698  scene handler, e.g., with /vis/scene/notifyHandlers, the first
699  viewer to get refreshed should trigger the display list rebuild, but
700  the second need not.  However, when the second viewer's turn comes,
701  the display lists are there, and are called, e.g.,
702  G4OpenGLStoredXViewer::DrawView calls
703  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
704  nothing appears on the screen.  To overcome this there is some
705  temporary code in G4VViewer::NeedKernelVisit which marks *all*
706  viewers to force a rebuild.  To see the symptoms, comment out that
707  temporary code and issue these commands:
708    /vis/verbose c
709    /control/verbose 2
710    /vis/scene/create
711    /vis/scene/add/volume
712    /vis/sceneHandler/create OGLSX
713    /vis/viewer/create ! ! 1
714    /run/beamOn
715    /vis/viewer/create ! ! 1
716    /vis/viewer/select viewer-0
717    /vis/viewer/viewpointThetaPhi 20 20
718    /vis/viewer/select viewer-1
719    /vis/viewer/viewpointThetaPhi 40 40
720    /vis/viewer/set/style surface
721    /vis/viewer/refresh
722    /vis/viewer/select viewer-0
723    /vis/viewer/refresh
724    /vis/viewer/select viewer-1
725    /vis/viewer/set/style wireframe
726    /vis/scene/notifyHandlers
727  You may have to do this too:
728    /vis/viewer/select viewer-0
729    /vis/scene/notifyHandlers
730  One of the viewers is empty.  Curious!!
731
7329th August 2001  John Allison  (vis-V03-02-10-00)
733- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
734- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
735  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
736  picked up by inheritance anyway.
737- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
738- Corrected order of calling base class functions in
739  G4OpenGLStoredSceneHandler::Begin/EndModeling.
740
74124th July 2001  John Allison  (vis-V03-02-06)
742- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
743
74414th July 2001  John Allison (opengl-V03-02-00)
745- Fixed crash in optimised mode: added Initialise() to viewers so
746  that windows are opened after viewers are fully constructed.
747
7482nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
749- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
750
7517th March 2001  John Allison
752- Changed char* to const char* in many places and that gave problems in
753  calls to Xt and Xm.  Hope all's OK.  Differences:
754    cvs diff -r vis-V03-00-06 vis-V03-00-07
755
75625th January 2001  John Allison  (opengl-V03-00-00)
757- Implemented running re-calculation of up-vector in the case of "object
758  rotation" (lights move with camera) to prevent "flipping" of view when
759  camera passes through up-vector.  Note that the default is "camera
760  rotation" (lights do not move with camera, i.e., remain fixed relative
761  to object) so the default is that this "flipping" can happen.  To set
762  "object rotation" (lights move with camera) use
763  /vis/lights/move_with_camera true (soon to be
764  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
765  on Rotation Panel in OpenGLXm mode.
766- Changed some objects to references for efficiency.  E.g.:
767  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
768
76922nd May 2000  John Allison  (opengl-V01-01-00)
770- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
771  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
772    static XVisualInfo* vi_single_buffer;
773    static XVisualInfo* vi_double_buffer;
774- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
775  G4OpenGLXViewer.
776- Protected double deletion of window in destructors of G4OpenGLXmViewer
777  and G4OpenGLXViewer (Guy Barrand).
778- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
779- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
780  constructors.
Note: See TracBrowser for help on using the repository browser.
