171
17221st August 2007 John Allison (opengl-V09-00-00)
173- Removed redundant G4OpenGLXViewerMessenger.
174
17525th May 2007 John Allison (opengl-V08-03-03)
176- G4OpenGLSceneHandler and G4OpenGLXViewerMessenger:
177 Fixed gcc-4.1.2 compiler warnings.
178
17925th May 2007 John Allison (opengl-V08-03-02)

181
18224th May 2007 John Allison (opengl-V08-03-01)
183- Fixes for SUN.

187- Bug fixes:
188 o Correct path /vis/ogl/set/printMode.
189 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
190 and "/vis/ogl/printEPS").
191
1928th May 2007 John Allison (opengl-V08-02-06)
193- Moved vectored PostScript printing to G4OpenGLViewer.
194- /vis/ogl/printEPS should work for all viewers, including Win32.
195- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
196 effective on X windows (and still somewhat buggy).
197
1984th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
199- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
200 for OGL*Win32. Still doesn't work for OGL*Xm.
201
2023rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
203- G4OpenGLStoredSceneHandler:
204 o Re-organised display lists on a per-primitive basis, i.e., one
205 display list per primitive. (This is so that, except for text,
206 the colour - or, rather, intensity - can be brought out of the
207 display list into the TOList (Transient Object List) and
208 controlled for the Display-by-Time feature. Previously, if more
209 than one primitive were drawn between BeginPrimitives and
210 EndPrimitives, it would finish up all in one display list, colour
211 commands included. Rationalises and fixes a rare bug in the
212 Display-by-Time feature - see August 2006.)
213 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
214 one primoitive to fit with the above re-organisation.
215- Implemented picking for OGLIX.
216
21725th March 2007 John Allison (opengl-V08-02-03)
218- Fix compiler warnings.
219
2208th February 2007 John Allison (opengl-V08-02-02)
221- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
222- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
223 .but not switched back. Not serious, because context was always set
224 before normal drawing.)
225
2269th January 2007 John Allison (opengl-V08-02-01)
227- Implemented bitmap markers for MarkerSizeType == screen. (The old
228 polygon implementation remains for MarkerSizeType == world.)
229- Added G4OpenGLBitMapStore to assist the above.
230- G4OpenGLXViewer::CreateGLXContext:
231 o Bug fix: Added missing break in colormap lookup routine.
232
2335th January 2007 John Allison (opengl-V08-02-00)
234- G4OpenGLSceneHandler.cc:
235 o Followed change of signature of GetLineWidth in visman-V08-02-00.
236 o Minor efficiency improvements.
237
23821st November 2006 John Allison (opengl-V08-01-09)
239- Fixed compiler warnings.
240
2411st November 2006 John Allison (opengl-V08-01-08)
242- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
243 actually initiates a print, rather than set a flag for printing.
244
24524th October 2006 John Allison (opengl-V08-01-07)
246- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
247- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
248
24919th September 2006 John Allison (opengl-V08-01-06)
250- Added time origin for light front.
251- Added /vis/ogl/set/transparency.
252- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
253
2544th September 2006 John Allison (opengl-V08-01-05)
255- Implement cutaways.
256- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
257 primitives (see detector being drawn).
258- /vis/oglx/set/printEPS: change parameter default to true.
259
26030th August 2006 John Allison (opengl-V08-01-04)
261- G4OpenGLSceneHandler:
262 o Implemented line width.
263 o Switched off back face culling when clipping so that the inside of
264 volumes can be seen.
265 o Added CreateSection/CutawayPolyhedron to exploit generic
266 sectioning (DCUT) and cutaways. Currently not activated due to
267 instabilities in BooleanProcessor. Local sectioning still active
268 but broken (at least on Mac) due to apparent change in effect of
269 clipping planes (polyhedron edges not reconstructed).
270 o Rationalised calculation of marker size.
271- G4OpenGLStoredSceneHandler:
272 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
273 o Pick up time range from G4VisAttributes.
274- G4OpenGLViewer(Messenger):
275 o Added position and colour to /vis/ogl/set/displayHeadTime.
276 o Added /vis/ogl/set/displayLightFront.
277- G4OpenGLStoredViewer.cc:
278 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
279 o Added position and colour to DisplayHeadTime.
280 o Added DisplayLightFront.
281
28216th August 2006 John Allison (opengl-V08-01-03)
283- Corrected Solaris compilation error.
284- Added /vis/ogl/set/fade and displayHeadTime.
285
28614th August 2006 John Allison (opengl-V08-01-02)
287- Needs visman-V08-01-02.
288- G4OpenGLStored: Implemented display-by-time. Only available in
289 stored mode at present. Only implemented for circle, square,
290 polyline and polymarker at present, enough for currently available
291 trajectory models. Time is communicated via G4AttValues.
292- Added G4OpenGLViewerMessenger.
293- Added /vis/ogl/set/startTime and endTime of displayed objects.
294- All factories: Instantiated G4OpenGLViewerMessenger.
295- G4OpenGLViewer: Added fStart/EndTime.
296- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
297 spewPrimitiveEPS and spewSortedFeedback.
298
29917th July John Allison (opengl-V08-01-01)
300- Added /vis/oglx/set/printEPS (prints eps file on every update).
301
3023rd July 2006 John Allison (opengl-V08-01-00)
303- Elimination of redundant variable doublebuffer and implementation of
304 FinishView in all viewers.
305
30630th May 2006 Joseph Perl (opengl-V08-00-08)
307- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
308 variable seems to have random behavior and should be assumed false for
309 this viewer.
310
31129th May 2006 Joseph Perl (opengl-V08-00-07)
312- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
313 Removed common FinishView and instead made separate FinishView for the two different
314 versions of this viewer since each wants a different buffer swapping behaviour.
315
31612th May 2006 John Allison (opengl-V08-00-06)
317- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
318
31928th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
320- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
321 recomputing transients.
322
32324th April 2006 John Allison (opengl-V08-00-04)
324- Fixed compilation problem on Windows.
325
32619th April 2006 John Allison (opengl-V08-00-03)
327- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
328 G4OpenGLImmediateSceneHandler:
329 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
330 greps-V08-00-02).
331 o Migrated to direct access to G4PhysicalVolumeModel.
332- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
333 of display lists in DrawView.
334
33514th March 2006 John Allison (opengl-V08-00-02)
336- Refined display list building and re-drawing algorithm.
337 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
338 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
339- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
340 re-use algorithm. In test19 with global culling off, numbers of
341 display lists used are:
342 o 191 No re-use:
343 o 73 Before this change: re-use except replicas (includes parameterised).
344 o 33 After this change: re-use except parameterised and replicas in radius.
345
34626th January 2006 John Allison (opengl-V08-00-01)
347- Coworks with visman-V08-00-04 (removed fModified).
348- Removed references to fModified.
349- Tidying: Removed unnecessary ClearView.
350- G4OpenGLSceneHandler.cc: Added some (commented out) code for
351 possible future implementation of 2D drawing.
352- G4OpenGLXViewer.cc: Improved exception printing.
353
35411th January 2006 John Allison (opengl-V08-00-00)
355- Improved efficiency: all DrawView's:
356 o Don't call ClearView.
357 o Set flag so SetView will not be called in ProcessView.
358 o Leave background colour to ClearView.
359- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
360- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
361 for current viewer.
362
36324th November 2005 John Allison (opengl-V07-01-09)
364- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
365
36622nd November 2005 John Allison (opengl-V07-01-08)
367- Added G4OpenGLXmViewerMessenger.
368- Corrected text position.
369- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
370
37117th November 2005 Gabriele Cosmo
372- Fixed settings of background style for WIN32 viewers.
373
37413th November 2005 John Allison (opengl-V07-01-07)
375- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
376
37713th October 2005 John Allison (opengl-V07-01-06)
378- Allowed any colour background.
379- Implemented non-uniform scaling.
380- Migration to <sstream>.
381
38229th September 2005 John Allison (opengl-V07-01-05)
383- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
384 scene handler.
385- Re-implemented transparency button in OpenGLXm.
386
38713th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
388- Implemented white background for all OGL viewers.
389- G4OpenGLSceneHandler.cc:
390 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
391 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
392 o Corrected GetTextColour(text).
393 o Corrected GetColour(polyhedron).
394
3955th September 2005 John Allison (opengl-V07-01-03)
396- Bug fix: stored transparent objects were being lost.
397
3982nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
399- Bug fix: edgeflags problem introduced with smooth shading in
400 opengl-V07-01-00.
401- Implementation of a "better algorithm" for the rendering of
402 transparent polyhedron objects. It renders all opaque objects
403 first, then renders the transparent objects with the depth buffer in
404 read-only mode (see OpenGL Programming Guide). It uses the new
405 facility in G4VSceneHandler::ProcessScene for an optional second pass
406 of the run-duration models in the scene. Note this algorithm is
407 still only an approximation. It will still give the wrong blended
408 colour if two transparent objects are rendered front first. For
409 nested transparent objects, this is unfortunate, because
410 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
411 in such a way that mothers come first. Also, there is no guaranteed
412 relationship between the order of rendering and the depth of two
413 transparent objects if they are at the same level or in different
414 branches of the hierarchy. Still, the only error will be an
415 incorrect colour - the objects will still give the appearance of
416 transparency, so it's a pretty good algorithm. (An even better
417 algorithm would be to attempt to render the facets in depth order,
418 deepest first. But how do you calculate the depth - centre of area,
419 deepest corner? One can still imagine pathalogical cases that would
420 sometimes give the wrong colour. Also, for stored mode, the order
421 is fixed in a display list so when the user rotates the view, one
422 would lose the depth ordering. I think we have to accept that
423 blending in OpenGL is only ever an approximation. For accurate
424 blending, use RayTracer.)
425
42628th August 2005 John Allison (opengl-V07-01-01)
427- Half-way implementation of rendering of transparent polyhedron
428 objects. In this implementation, no account is taken of the order
429 of rendering. Transparent objects are rendered with depth testing
430 off so that objects behind can still be seen. But this means that
431 opaque objects in front do not obscure them - and they jolly well
432 should! A better algorithm is to render all opaque objects first,
433 then render the transparent objects with the depth buffer in
434 read-only mode (see OpenGL Programming Guide). This is going to
435 take a little more thought - see opengl-V07-01-02.
436
43720th July 2005 John Allison (opengl-V07-01-00)
438- Introduced smooth shading, taking advantage of hitherto un-noticed
439 feature of HepPolyhedron::GetNextFacet that calculates the normals
440 at each vertex so that curved surfaces are rendered more
441 realistically (Gouraud shading).
442- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
443- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
444 the default window size. It used to be 400x400, hardcoded in
445 G4OpenGLXmViewer.cc, but now it picks up the
446 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
447 The user may change it on the command line, e.g:
448 /vis/open OGLSXm 500
449 or
450 /vis/viewer/create ! ! 500
451
45230th May 2005 John Allison (opengl-V07-00-03)
453- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
454 map of vectors in G4OpenGLFontBaseStore.)
455
4564th May 2005 John Allison (opengl-V07-00-02)
457- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
458 was taken out to prevent recursive calling, but that seems to be OK,
459 and it is needed to implement refresh at end of event/run.)
460
46122nd April 2005 John Allison (opengl-V07-00-01)
462- Rationalised work of opengl-V07-00-00. Functionality unchanged.
463 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
464 o In all concrete viewers, added call to CreateFontLists().
465 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
466 o There is no longer a need to implement in the XmViewer, since it
467 now inherits. Thus the font code now only appears once for X.
468 o Awaiting implementation for WIN32.
469
47017th April 2005 John Allison (opengl-V07-00-00)
471- Based on vis-V07-00-13.
472- Implemented text for X-Windows viewers. Uses glXUseXFont, which
473 creates display lists for nominated fonts. Simple-minded scheme in
474 which each viewer creates its own font display lists for a variety
475 of sizes, which are accessed by the scene handler through a new
476 class, G4OpenGLFontBaseStore. Affected methods:
477 G4OpenGLXViewer::CreateMainWindow()
478 G4OpenGLXmViewer::CreateMainWindow()
479 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
480
48118th November 2004 John Allison (opengl-V06-02-07)
482- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
483
48415th November 2004 Guy Barrand
485- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
486 to see trajectories (for example with N03). Correct so that
487 ShowView do a FinishView that does : glFlush, wglSwapBuffer
488 and empty the Windows message queue.
489
49022nd September 2004 John Allison (opengl-V06-02-06)
491- doxygen output to tmp area.
492- Trap non-regular polyhedrons.
493
49413th September 2004 Gabriele Cosmo (opengl-V06-02-05)
495- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
496 to allow for porting on CLHEP-1.9.X series.
497
49823rd July 2004 John Allison
499- Draws auxiliary edges if required.
500- Added auxiliary edge button.
501
50216th July 2004 John Allison (opengl-V06-02-04)
503- Refinements to hidden line, hidden surface removal.
504
50514th July 2004 John Allison (opengl-V06-02-03)
506- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
507
50813th July 2004 John Allison (opengl-V06-02-02)
509- Hidden line *and* hidden surface removal now works.
510
5119th July 2004 John Allison (opengl-V06-02-01)
512- Fixed long-standing problem with hidden line removal.
513- Improved messages on failure to get visual.
514- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
515 systems provided by default anyway, so no effect.
516
5171st July 2004 John Allison (opengl-V06-02-00)
518- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
519- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
520
52118th June 2004 Gunter Folger (geant4-06-02)
5229th June 2004 Gabriele Cosmo (vis-V06-01-03)
5237th June 2004 Gabriele Cosmo (vis-V06-01-02)
524- GNUmakefile and disclaimer changes - see visualization/History.
525
5269th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
527- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
528
5297th April 2004 Guy Barrand
530- visualization/OpenGL/* : use the G4OpenGL.hh file.
531- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
532 the include of gl/gl.h and gl/glu.h that may be platform dependant.
533 It permits to rm some #ifdef WIN32 spread in the code. It opens also
534 the way to the usage of the Apple OpenGL on a Mac.
535
53617th February 2004 John Allison (opengl-V06-00-00)
537- Fixed bug #581: wrong order of statements in
538 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
539
5404th October 2003 Gabriele Cosmo (vis-V05-02-01)
541- GNUmakefile:
542 o replaced "digits+hits" with "digits_hits".
543- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
544
54522nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
546- Cosmetic change to regularise names:
547 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
548 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
549
55023rd June 2003 Guy Barrand (opengl-V05-01-02)
551- Commit a first implementation of G4OpenGLWin32Viewer.
552
55310th June 2003 Gabriele Cosmo (opengl-V05-01-01)
554- More fixes for warnings in viewers classes.
555- Added inclusion of <windows.h> for WIN32 platforms when GL headers
556 are included.
557
55805th June 2003 Gabriele Cosmo (opengl-V05-01-00)
559- Fixes for porting compilation on WIN32:
560 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
561 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
562 since declared 'obsolete' in WIN32 platforms.
563
56427th November 2002 John Allison (vis-V04-01-08)
565- Improved algorithm of CompareForKernelVisit.
566
56711th November 2002 John Allison (opengl-V04-01-02)
568- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
569- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
570 call default but there as a marker and encourager.
571- Added tracking and digits+hits/hits to GNUmakefile.
572
57316th October 2002 John Allison (opengl-V04-01-01)
574- Fix for WIN32. Now compiles but viewer not implemented.
575
57624th June 2002 John Allison (opengl-V04-01-00)
577- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
578
57910th June 2002 John Allison (opengl-V04-00-03)
580- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
581
5826th June 2002 John Allison (opengl-V04-00-02)

584
58523rd February 2002 John Allison (opengl-V04-00-01)
586- Changes to encourage compilation on Windows in preparation for
587 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
588 glx.h, unistd.h and assert.h.
589
59024th August 2001 John Allison (vis-V03-02-13)
591- Limited the printing of warnings in
592 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
593
59414th August 2001 John Allison (vis-V03-02-11)
595- Improved KernelVisitDecision.
596- Fixed a few small bugs in multiple "stored" viewers, but see next item.
597- There's an outstanding bug in OpenGL Stored. If there is more than
598 one viewer controlled by a scene handler, after a ClearStore on the
599 scene handler, e.g., with /vis/scene/notifyHandlers, the first
600 viewer to get refreshed should trigger the display list rebuild, but
601 the second need not. However, when the second viewer's turn comes,
602 the display lists are there, and are called, e.g.,
603 G4OpenGLStoredXViewer::DrawView calls
604 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
605 nothing appears on the screen. To overcome this there is some
606 temporary code in G4VViewer::NeedKernelVisit which marks *all*
607 viewers to force a rebuild. To see the symptoms, comment out that
608 temporary code and issue these commands:
609 /vis/verbose c
610 /control/verbose 2
611 /vis/scene/create
612 /vis/scene/add/volume
613 /vis/sceneHandler/create OGLSX
614 /vis/viewer/create ! ! 1
615 /run/beamOn
616 /vis/viewer/create ! ! 1
617 /vis/viewer/select viewer-0
618 /vis/viewer/viewpointThetaPhi 20 20
619 /vis/viewer/select viewer-1
620 /vis/viewer/viewpointThetaPhi 40 40
621 /vis/viewer/set/style surface
622 /vis/viewer/refresh
623 /vis/viewer/select viewer-0
624 /vis/viewer/refresh
625 /vis/viewer/select viewer-1
626 /vis/viewer/set/style wireframe
627 /vis/scene/notifyHandlers
628 You may have to do this too:
629 /vis/viewer/select viewer-0
630 /vis/scene/notifyHandlers
631 One of the viewers is empty. Curious!!
632
6339th August 2001 John Allison (vis-V03-02-10-00)
634- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
635- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
636 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
637 picked up by inheritance anyway.
638- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
639- Corrected order of calling base class functions in
640 G4OpenGLStoredSceneHandler::Begin/EndModeling.
641
64224th July 2001 John Allison (vis-V03-02-06)
643- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
644
64514th July 2001 John Allison (opengl-V03-02-00)
646- Fixed crash in optimised mode: added Initialise() to viewers so
647 that windows are opened after viewers are fully constructed.
648
6492nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
650- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
651
6527th March 2001 John Allison
653- Changed char* to const char* in many places and that gave problems in
654 calls to Xt and Xm. Hope all's OK. Differences:
655 cvs diff -r vis-V03-00-06 vis-V03-00-07
656
65725th January 2001 John Allison (opengl-V03-00-00)
658- Implemented running re-calculation of up-vector in the case of "object
659 rotation" (lights move with camera) to prevent "flipping" of view when
660 camera passes through up-vector. Note that the default is "camera
661 rotation" (lights do not move with camera, i.e., remain fixed relative
662 to object) so the default is that this "flipping" can happen. To set
663 "object rotation" (lights move with camera) use
664 /vis/lights/move_with_camera true (soon to be
665 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
666 on Rotation Panel in OpenGLXm mode.
667- Changed some objects to references for efficiency. E.g.:
668 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
669
67022nd May 2000 John Allison (opengl-V01-01-00)
671- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
672 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
673 static XVisualInfo* vi_single_buffer;
674 static XVisualInfo* vi_double_buffer;
675- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
676 G4OpenGLXViewer.
677- Protected double deletion of window in destructors of G4OpenGLXmViewer
678 and G4OpenGLXViewer (Guy Barrand).
679- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
680- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
681 constructors.
