  9 ## 2023-09-27 Stewart Boogert (greps-V11-01-06)
 10 - Added centre calculation to HepPolyhedron for use in vis systems
 11 
 12 ## 2023-07-01 John Allison (greps-V11-01-05)
 13 - G4VisAttributes:
 14   - Trap under-limit requested number of line segments per circle for polyhedral
 15     representation of circular surfaces.
 16     - An under-limit request sets number to minimum (3). (3 may sound ridiculously
 17       small, but it's OK for axes and arrows.)
 18 
 19 ## 2023-05-09 John Allison (greps-V11-01-04)
 20 - Coworks: visman-V11-01-10 and interfaces-V11-01-15.
 21 - G4SceneTreeItem:
 22   - Add data member fExpanded.
 23 
 24 ## 2023-04-14 John Allison (greps-V11-01-03)
 25 - Co-working: visman-V11-01-04, interfaces-V11-01-11, opengl-V11-01-06,
 26   openinventor-V11-01-04, vis_toolssg-V11-01-05.
 27 - New Scene Tree Phase 2 - first implementation of a no-frills GUI-side
 28   - See visualization/management/History for full description.
 29 - G4SceneTreeItem:
 30   - Make it explicit that the default copy constructor and assignment
 31     operator copy the whole tree hanging from this item.
 32   - Replace Dump by DumpSingleItem to make its function explicit.
 33   - Move DumpTree from static function to member function.
 34   - Improve comments.
 35 
 36 ## 2023-04-07 John Allison (greps-V11-01-02)
 37 - G4SceneTreeItem: enum Type: Add "pvmodel" special case.
 38 
 39 ## 2023-03-28 John Allison (greps-V11-01-01)
 40 - Add `G4SceneTreeItem.hh/.cc`.
 41 - clang-tidy the above.
 42 - `G4AttValue.hh`: Add `~G4AttValue()= default`.
 43 
 44 ## 2022-12-12 Ben Morgan (greps-V11-01-00)
 45 - Remove obsolete GNUmakefile scripts
 46 
 47 ## 2022-11-17 Gabriele Cosmo (greps-V11-00-16)
 48 - Fixed compilation warnings for implicit type conversions on macOS/XCode 14.1.
 49 
 50 ## 2022-10-28 John Allison (greps-V11-00-15)
 51 - G4VVisManager: Add new virtual function DrawGeometry.
 52   - Draws a geometry tree starting at the specified physical volume.
 53   - This base class implementation is empty, i.e., the derived class
 54     implementation is not forced (as it would be if declared pure virtual).
 55 
 56 ## 2022-10-06 Gabriele Cosmo (greps-V11-00-14)
 57 - Fixed compilation warning on Intel/icx compiler for variable set
 58   but not used in HepPolyhedron::FindNodeNormal().
 59 
 60 ## 2022-10-03 Evgueni Tcherniaev (greps-V11-00-13)
 61 - HepPolyhedron: Fix minor coverity defect in operator<<
 62 
 63 ## 2022-09-19 John Allison (greps-V11-00-12)
 64 - G4VisAttributes: Fix formatting in operator<<
 65 
 66 ## 2022-09-14 Ben Morgan (greps-V11-00-11)
 67 - Apply clang-tidy fixes
 68 
 69 ## 2022-09-05 Ben Morgan (greps-V11-00-10)
 70 - Make G4intercoms a private dependency
 71 
 72 ## 2022-05-01 Evgueni Tcherniaev (greps-V11-00-09)
 73 - Faster version of HepPolyhedronTetMesh
 74 
 75 ## 2022-04-22 Evgueni Tcherniaev (greps-V11-00-08)
 76 - `G4Polyhedron`: added move constructor and move assignment
 77 
 78 ## 2022-04-10 Evgueni Tcherniaev (greps-V11-00-07)
 79 - `HepPolyhedron`, `G4Polyhedron`:
 80   - Added `HepPolyhedronBoxMesh`, `G4PolyhedronBoxMesh`
 81   - Selection of most coplanar neighboring facets in `JoinCoplanarFacets()`
 82 
 83 ## 2022-04-06 John Allison (greps-V11-00-06)
 84 - `G4Visible`:
 85   - Add "user" data member `fInfo`, with access and operator<< functions.
 86   - This is intended to offer the user/developer a way of communicating
 87     information. For example, with "special mesh rendering" in G4 vis, we
 88     use it to communicate the name of the material - heart, lungs, etc. - to
 89     the viewer and the vis user can identify the different organs.
 90 - `G4VMarker`:
 91   - Previously, `fInfo` was here. It has been moved to `G4Visible`.
 92   - `G4VMarker` *is* a `G4Visible`, so it still has a `fInfo` data member
 93     by inheritance (and access and operator<< functions).    
 94 
 95 ## 2022-04-05 Evgueni Tcherniaev (greps-V11-00-05)
 96 - Implemented `HepPolyhedron::JoinCoplanarFacets()`
 97 
 98 ## 2022-04-01 Evgueni Tcherniaev (greps-V11-00-04)
 99 - `HepPolyhedron`, `G4Polyhedron`:
100   - Added `HepPolyhedron(Nvert, Nface)`, `G4Polyhedron(nvert, nface)`
101   - Added derived classes `HepPolyhedronTetMesh`, `G4PolyhedronTetMesh`
102   - Added `SetVertex()`, `SetFacet()`
103   - Made public `SetReferences()`, `InvertFacets()`;
104 
105 ## 2022-01-28 Ben Morgan (greps-V11-00-03)
106 - Replace `geant4_global_library_target` with direct file inclusion and
107   call to `geant4_add_category` to define library build from source modules.
108 - Make DLL export symbol a CMake module-level compile definition to aid
109   future modularization
110 
111 ## 2022-01-21 Evgueni Tcherniaev (greps-V11-00-02)
112 - Revised HepPolyhedronEllipsoid, it fixes visibility
113   of edges in case of cut ellipsoid
114 
115 ## 2021-12-11 John Allison (greps-V11-00-01)
116 - G4VisExtent::Transform: Use const auto& to avoid copying.
117 
118 ## 2021-12-10 Ben Morgan (greps-V11-00-00)
119 - Change to new Markdown History format
120

123 # History entries prior to 11.0
124 
125 28 October 2021 Guy Barrand (greps-V10-07-13)
126 - sources.cmake: declare G4Plotter.hh,.cc.
127 - G4VGraphicsScene: have:
128     virtual void AddPrimitive (const G4Plotter&) = 0;
129 - G4Plotter.hh,.cc: some kind of "high level" primitive
130   to capture "what is plotted" (tools::histo:h1d, h2d for the moment) and the style of a plotter.
131   Style description is done by handing named lists of (parameter,value). It is sufficently
132   generic to be usable by various implementations of a plotter. It is assumed that
133   a plotter manages a grid of "regions" to visualize various histograms in a same
134   representation/view/viewport (concept similar to the "zones" in the CERN-PAW plotter).
135 
136 25 October 2021 Ben Morgan (greps-V10-07-12)
137 - Use G4StrUtil functions replacing deprecated G4String member functions

146 
147 30 June 2021  John Allison  (greps-V10-07-09)
148 - Revise vis models. See visualization/modeling/History for more details.
149 - Remove G4Scale. G4Scale is an anomaly. It is not a "primitive" (obviously),
150   but somehow, from the long distant past, it was implemented as though it was.
151   (/vis/scene/add/scale reimplemented with G4CallBackModel.)
152 
153 29 June 2021 Evgueni Tcherniaev (greps-V10-07-08)
154 - HepPolyhedron.cc: minor fix for Coverity
155 - BooleanProcessor.src: redundant std::move(polyhedron) replaced with
156   HepPolyhedron(polyhedron), it fixes complation warnings with c++20
157 
158 07 June 2021 John Allison (greps-V10-07-07)
159 - G4VGraphicsScene.hh:
160   o Introduce a new pure virtual function:

162 - G4VisAttributes.cc:
163   o Improve message in SetForceNumberOfCloudPoints.
164

168 12 May 2021 Evgueni Tcherniaev (greps-V10-07-05)
169 - added TriangulatePolygon(), RotateContourAroundZ()
170 - added HepPolyhedronPgon, HepPolyhedronPcon given by rz-contour
171 
172 06 May 2021 Gabriele Cosmo (greps-V10-07-04)
173 - Fixed shadowing compilation warning in G4Colours reported with gcc-11.
174 
175 18 March 2021 Ben Morgan (greps-V10-07-03)
176 - Fix typo in geant4_add_module that prevented install of greps headers
177 
178 15 March 2021 John Allison (greps-V10-07-02)

206 
207 13 February 2020  John Allison  (greps-V10-06-01)
208 - G4VisAttributes:
209   o Clarify that if number of cloud points (for cloud style drawing)
210     is <= 0, this is to be interpreted as under control of the viewer,
211     i.e., to be decided by the viewer. Otherwise this number is to be
212     drawn.
213   o Make 0 the default value.
214   o It may be changed with SetForceNumberOfCloudPoints.
215   o You may also force cloud drawing with SetForceCloud.
216

239 
240 19 February 2019  John Allison
241 - Included in vis-V10-05-12
242 - G4VisExtent:
243   o Replaced operator*(const G4Transform3D&) by
244     Transform(const G4Transform3D&).
245     (Note: operator* was only ever in a development version of Geant4.)
246 
247 31 January 2019  Ivana Hrivnacova (greps-V10-05-01)
248 - Merged GitHub PR #4: all Boolean operators now return G4bool.
249 
250 02 January 2018  John Allison (greps-V10-05-00)
251 - G4VisExtent: Add operator*(const G4Transform3D&).
252 
253 19 October 2018  John Allison (greps-V10-04-08)
254 - G4VisExtent: Add GetNullExtent.
255 
256 16 October 2018  John Allison (greps-V10-04-07)
257 - G4VisExtent: Add operator==.
258 
259 12 September 2018  John Allison (greps-V10-04-06)
260 - G4VVisManager: Add fDrawOverlapsFlag and access functions.
261   o This is intended to be inspected by methods capable of drawing
262     overlaps. See for example, CheckOverlaps in G4PVPlacement and
263     G4PVParameterised.
264 
265 22 May 2018  Gabriele Cosmo (greps-V10-04-05)
266 - Disabled deprecated static data member G4VisAttributes::Invisible for
267   Windows systems.
268 
269 24 April 2018  John Allison (greps-V10-04-04)
270 - Co-works vis-V10-04-04.
271 - G4VisAttributes: Cosmetic improvements.
272 
273 23 April 2018  John Allison (greps-V10-04-03)
274 - Co-works vis-V10-04-04.
275 - Replaced DBL_MAX by G4VisAttributes::veryLargeTime = 1.e100*CLHEP::ns,
276   about 1.e75 billion years!! The problem is that DBL_MAX (1.79769e+308)
277   is dimensionless, so we compromise with something a little less vast,
278   but which is in G4 internal units.
279 
280 18th January 2018  Gabriele Cosmo (greps-V10-04-01)
281 - Updated GNUmakefile to add G4GREPS_ALLOC_EXPORT definition.
282 
283 18th January 2018  Ben Morgan (greps-V10-04-00)
284 - Fix unexported global data for WINDOWS_EXPORT_ALL_SYMBOLS
285 - New DLL build method identified that G4VisAttributes has a
286   static const member that is not declared dllexport/import.
287 - graphics_reps_defs.hh: New header to configure the needed
288   export/import keywords, using a macro G4GREPS_DLL
289 - CMakeLists.txt: Add -D flag G4GREPS_ALLOC_EXPORT when
290   building the library to make export mode.
291 - G4VisAttributes.hh: Mark static const G4VisAttributes data
292   using G4GREPS_DLL to ensure export/import.
293 
294 6th October 2017  John Allison  (greps-V10-03-07)
295 - Rationalised:
296   o Colour map no longer G4ThreadLocal (no need). May be used from
297     non-master threads.
298   o Move InitialiseColourMap from private to public. In future vis tags
299     the map will be initialised from the vis manager.
300 
301 13th September 2017  John Allison  (greps-V10-03-06)
302 - HepPolyhedron.h: Reverted default number of line segments per circle:
303   #define DEFAULT_NUMBER_OF_STEPS 24
304   (72 lines per circle gives trouble in the Boolean Processor, so until that
305   is fixed we revert to 24.)
306 
307 1st August 2017  John Allison  (greps-V10-03-05)
308 - G4AttDefStore: Shared (i.e., no longer thread local). Added mutex.
309 
310 10th May 2017  John Allison  (greps-V10-03-04)
311 - G4Colour: Added Set functions for components.
312 
313 25th April 2017  John Allison  (greps-V10-03-03)
314 - G4Colour& operator += (const G4Colour& rhs) {*this = rhs; return *this;}
315   // Note: This is required by RayTracer in its use of G4THitsMap.
316   // Adding colours, without also taking brightness into account, does not make
317   // sense, so let us make it synonymous with operator=, which is, I guess,
318   // equivalent to covering the old colour with the new, like a coat of paint.
319 
320 22nd February 2017  John Allison  (greps-V10-03-01)
321 - Requires visman-V10-03-03.
322 - Removed G4VisExtent::NullExtent.
323 
324 3rd November 2016  John Allison  (greps-V10-02-10)
325 - Fix typo in previous tag.
326

329 
330 3rd November 2016  John Allison  (greps-V10-02-08)
331 - HepPolyhedron.h: Changed default number of line segments per circle:
332   #define DEFAULT_NUMBER_OF_STEPS 72
333 
334 6th September 2016  Makoto Asai (greps-V10-02-07)
335 - Co-works with digits_hits-V10-02-06, vis-V10-02-12
336 - include/G4VGraphicsScene.hh
337      It accepts both G4TMitsMap<G4StatDouble> and G4THitsMap<G4double>.
338 
339 2nd September 2016  Makoto Asai (greps-V10-02-06)
340 - Co-works with digits_hits-V10-02-05, vis-V10-02-10
341 - include/G4VGraphicsScene.hh
342      Build-in scorer now uses G4TMitsMap<G4StatDouble> instead of
343      G4THitsMap<G4double>.
344 
345 31st August 2016  John Allison  (greps-V10-02-05)
346 - Co-works vis-V10-02-09.
347 - G4VGraphicsScene.hh:
348   o Added
349     virtual void AddSolid (const G4Orb&) = 0;
350     virtual void AddSolid (const G4Ellipsoid&) = 0;
351   o Tidied.
352 
353 7th August 2016  John Allison  (greps-V10-02-03)
354 - G4VisAttributes.icc: Removed extraneous semi-colon.
355 
356 7th August 2016  John Allison  (greps-V10-02-02)
357 - G4VisAttributes:
358   o Added flag for force auxiliary edge visibility, i.e., to record
359     if the user has asked for forcing, while the value forced - visible
360     or invisible - is recorded in another flag.
361   o Introduced default argument - "true" - for:
362     SetVisibility, SetDaughtersInvisible, SetForceWireframe,
363     SetForceSolid, SetForceAuxEdgeVisible.
364   o Improved logic for setting force drawing style and auxiliary edge
365     visibility.
366   o Moved above methods from .icc to .cc.
367   o Moved static inline method GetMinLineSegmentsPerCircle to .icc.
368 
369 14th July 2016  John Allison  (greps-V10-02-01)
370 - G4VisAttributes::GetInvisible():
371   o Changed to use a static instance instead of G4VisAttributes::Invisible.
372   o Moved implementation to .cc file.  Now it is non-inline.
373 - G4VisAttributes::Invisible:
374   o Deprecated. It is a static instance and does not always instantiate
375     properly on Windows.
376 
377 1st March 2016  Gabriele Cosmo  (greps-V10-02-00)
378 - Use "" instead of <> for internal header inclusion in
379   HepPolyhedronProcessor.h.
380 
381 26th April 2015  John Allison  (greps-V10-01-03)
382 - HepPolyhedron: Minor fix for Coverity.
383 
384 6th March 2015  John Allison  (greps-V10-01-02)
385 - HepPolyhedron: Corrected a long-standing spelling mistake:
386   o indeces should be indices;
387   o verteces should be vertices.
388   This is reflected in the method names, but the old names have been
389   kept for backwards compatibility.
390

416 
417 4th February 2014  John Allison  (greps-V10-00-04)
418 - Reverted to greps-V10-00-01.
419 - greps-V10-00-03: Was incorrectly tagged.
420 
421 20th December 2013  Mathieu Karamitros  (greps-V10-00-02)
422 - G4VisExtent: Enable accessing data using indexes
423 
424 11th December 2013  John Allison  (greps-V10-00-01)
425 - Introduced operator<< for const reference G4AttDefs map.
426 - Deprecated const pointer equivalent.

442 
443 19th September 2013  Makoto Asai (greps-V09-06-10)
444 - Introducing G4VVisManager::IgnoreStateChanges() virtual method.
445   This method should be invoked by a class that has its own event loop,
446   such as the RayTracer, material scanner, etc. If the argument is true,
447   the following state changes among Idle, GeomClosed and EventProc are
448   caused by such a class, and thus not by the ordinary event simulation.
449   The same method with false should be invoked once such an event loop
450   is over.
451 
452 17th September 2013  Makoto Asai (greps-V09-06-09)
453 - G4Colour now has a dummy += operator.
454 
455 12th September 2013  Makoto Asai (greps-V09-06-08)

457   by G4WorkerRunManager so that G4VisManager will get noticed at the
458   end of event of each worker thread.
459 
460 12th September 2013  Makoto Asai (greps-V09-06-07)
461 - Remove G4ThreadLocal keyword from G4VVisManager.

474     constructors.
475   o Allows creation of nm-sized objects.
476   o Fixes bug report 1452.
477 
478 14th February 2013 Jean Jacquemier
479 - Removed modifcations G4AttCheck.cc and G4DimentionedTypeUtil.cc for G4UnitTable
480   ( see  TAG greps-V09-06-02 ). These modifications will be done once

492 
493 1st October 2012  John Allison (greps-V09-05-14)
494 - G4DimensionedType: Another attempt to keep compilers happy:
495   o Created G4DimensionedTypeUtils.cc.
496   o Moved "Helper class" HasName and utility function GetUnitValue from
497     G4DimensionedType.hh to G4DimensionedTypeUtils.cc inside a new
498     namespace, G4DimensionedTypeUtils.
499 
500 27th September 2012  John Allison (greps-V09-05-13)
501 - G4DimensionedType.hh:
502   o Reverted to r53697.
503   o The last 3 tags cure the clang warning but cause run-time problems with

511 - G4DimensionedType.hh: Specifically defined G4DimensionedTypeNameSpace::GetUnitValue,
512   which keeps clang happy.  Hopefully other compilers too.
513 
514 15th August 2012  John Allison (greps-V09-05-10)
515 - G4DimensionedType.hh: Introduced G4DimensionedTypeNameSpace to replace an
516   un-name namespace to keep the clang compiler happy and improve the lives
517   of system testers.
518 
519 June 11, 2012 G.Cosmo (greps-V09-05-09)
520 - Explicitly use inclusion of headers for system of units and physical

567 - BooleanProcessor.src: Saved one instruction.
568   o No need to evaluate "point *= (1./nnode)" unless nnode > 1.
569   o (Also suppresses Coverity warning about division by zero.)
570 
571 11th November 2011  John Allison  (greps-V09-04-10)
572 - Fixed most Coverity warnings.
573 
574 2nd November 2011  John Allison  (greps-V09-04-09)

581 
582 29th September 2011  John Allison  (greps-V09-04-08)
583 - G4DimensionedType.hh:
584   o Reversed action of 27th Sep.  Warnings are false.  Function is needed.
585 
586 27th September 2011  John Allison  (greps-V09-04-07)
587 - G4DimensionedType.hh:
588   o Commented out unused function to suppress project warnings.

591 - G4VMarker.hh, G4Circle.hh, G4Square.hh, G4Polymarker.hh, G4Text.hh:
592   o Tidied.
593 - greps-V09-04-06: Inadvertent tag.
594 
595 16th September 2011  John Allison  (greps-V09-04-05)
596 - Migrated to new G4Exception.
597 
598 2nd August 2011  John Allison  (greps-V09-04-04)
599 - G4PolyhedronArbitrary:  Added SetReferences and InvertFacets.
600   SetReferences is necessary at the end to complete the polyhedron.
601   It particularly matters if the polyhedron suffers subsequent
602   boolean operations.
603   InvertFacets can be useful.
604 
605 1st March 2011  John Allison  (greps-V09-04-03)
606 - BooleanProcessor.cc:
607   o Changed cout to G4cout, etc.

619 
620 7th December 2010  John Allison
621 - Fixed Coverity warnings.
622 
623 6th December 2010  John Allison
624 - G4Visible.cc::operator!=: protect zero vis attributes pointers.
625 - G4Visible.cc::operator=: delete allocated vis attributes (fixes
626   memory leak).
627 
628 30th May 2010  John Allison  (greps-V09-03-02)
629 - G4VVisManager: Added Draw(const G4VDigi&) and FilterDigi(const G4VDigi&).

632 29th May 2010  John Allison  (greps-V09-03-01)
633 - G4VVisManager:
634   o Removed IsDefaultDrawTrajectory.  A better way is...
635   o Added DispatchToModel(const G4VTrajectory&), i.e., without i_mode, to
636     distinguish usage and in preparation for i_mode migration.
637 
638 7th May 2010  John Allison  (greps-V09-03-00)
639 - G4VVisManager: Added a public static boolean flag,
640   IsDefaultDrawTrajectory, to assist deprecation of i-mode trajectory
641   drawing parameter.  After 10.0, it can be removed.
642 
643 28th October 2009  John Allison  (greps-V09-02-03 coworks vis-V09-02-10)
644 - HepPolyhedron:
645   o Removed static instance of BooleanProcessor.
646   o Removed IsErrorBooleanProcess.  (Use HepPolyhedronProcessor instead -
647     see, e.g., G4PhysicalVolumeModel.)
648 - HepPolyhedronProcessor.src: Replaced printf with G4cout.
649 
650 20th October 2009  Guy Barrand  (greps-V09-02-02 coworks vis-V09-02-09)
651 - HepPolyhedronProcessor : class to handle "overall shifting" in case
652   of doing multiple boolean operations. This permited to solve most
653   tricky cases in LHCb visualization.
654 - HepPolyhedron : handle the ierr variable on the BooleanProcessor.execute.
655 - BooleanProcessor.src : modifs coming from LHCb to "loop on shifts"
656   to attempt solving the "coplanar faces cases".
657 - BooleanProcessor.src : modifs coming from LHCb to optmize the code.
658 
659 20th October 2009  John Allison  (greps-V09-02-02 coworks vis-V09-02-07)

663 - G4VVisManager: Added NotifyHandlers.
664   Notify scene handlers (G4VGraphicsScene objects) that the scene
665   has changed so that they may rebuild their graphics database, if
666   any, and redraw all views.
667 
668 24th February 2009  John Allison  (greps-V09-02-00)
669 - G4VMarker:
670   o Added enum SizeType {none, world, screen};

707   to allow for porting on Intel-icc compiler.
708 
709 3rd April 2007  John Allison  (greps-V08-02-01)
710 - G4AttDefStore: now comprises utility functions in namespace
711   G4AttDefStore.  (Used to be a class with only static functions and
712   data members.)
713 - G4AttHolder: Made copy constructor and assignment private to enforce
714   proper usage.
715 
716 5th January 2007  John Allison  (greps-V08-02-00)
717 - G4VisAttributes:
718   o SetForceLineSegmentsPerCircle: Bug fix: Now correctly implements reset.
719   o Minor refinement: Introduced IsForceLineSegmentsPerCircle().
720 - G4Colour: Replaced static data members by static functions that
721   create and copy out the relevant colours.  (Static data members make
722   a lot of noise in the gdb debugger.  Anyway, are best avoided.)
723 
724 7th November 2006  John Allison  (greps-V08-01-11)
725 - HepPolyhedronEllipticalCone: Bug fix.
726 - G4Visible: Fixed possible minor (subsidiary) memory leak in SetVisAttributes.
727 - G4AttCheck: Cosmetic.
728 
729 2nd November 2006  John Allison  (greps-V08-01-10)

736   o G4AttDefStore: Removed GetName, introduced GetStoreKey.
737   o G4AttHolder:
738     ~ Removed GetAttDefsName.
739     ~ Replaced AddAttValues and AddAttDefs by a combined AddAtts.
740 
741 24th October 2006  John Allison  (greps-V08-01-08; co-works: vis-V08-01-08)
742 - G4VisAttributes: Change GetAttValues to CreateAttValues.  It creates
743   an expendable copy on the heap, thus following the behaviour of
744   CreateAttValues in trajectories, hits, etc.  This achieves consistency
745   of behaviour and user expectation; the user must delete after use.
746 - G4AttHolder: Remove CopyAndAddAttValues.  No longer needed after
747   above change to G4VisAttributes.
748 
749 21st October 2006  John Allison  (greps-V08-01-07)
750 - Added G4AttHolder.

755 
756 16th October 2006  John Allison  (greps-V08-01-05)
757 - Added operator<< for G4AttDefs:
758   std::ostream& operator<<
759     (std::ostream& os, const std::map<G4String,G4AttDef>* definitions)
760 - Improved output diagnostics.
761

791 - Co-works with vis-V08-01-01.
792 - G4VGraphicsScene.hh: Removed Establish/DecommissionSpecials.
793 - G4VisAttributes:
794   o Added ForceLineSegmentsPerCircle.
795   o Cosmetic re-ordering of methods,
796
