* TGLMatrix:
Add function Bool_t IsScalingForRender() that returns true if length of base
vectors is significantly different than unity.
* TGLPhysicalShape:
Cache state of fTransform.IsScalingForRender() in a bool member.
When this is true, enable automatic scaling of normals during rendering.
* TGLLogicalShape:
Add static Bool_t fgIgnoreSizeForCameraInterest allowing a user to prevent
RGL from hiding very small objects - at least a pixel is always drawn. One
should invoke:
TGLLogicalShape::SetIgnoreSizeForCameraInterest(kTRUE);

Implement central infractructure to allow eve-elements to support
internal multiple selection and highlightning of their sub-parts.
Use this in TEveDigitSet and its sub-classes TEveQuadSet and
TEveBoxSet.
Extend GL rendering and event-handling to support these operations.
eve/
====
* TEveElement - Add 3 new functions:
virtual TString GetHighlightTooltip();
virtual void UnSelected();
virtual void UnHighlighted();
* TEveSecondarySelectable - New secondary base-class for elements
supporting internal multiple selection / highlight.
* TEveDigitSet, TEveQuadSet, TEveBoxSet
- Sub-class TEveDigitSet from TEveSecondarySelectable.
- Implement functions needed for internal selection.
- Add common base-class TEveDigitSetGL for quad and box-set GL rendering.
* TEveChunkManager - Add support for restricted iteration.
TEveChunkManager::iterator accepts set<Int_t> for that purpose.
* TEveViewer - Add functions to handle additional mouse-hover signals
from TGLViewer.
* Other classes (all GL renderers) - Changes for additional argument
to TGLLogicalShape::DrawHighlight().
gl/
===
* TGLObject - Take AlwaysSecondarySelect() into account when deciding
whether to use DL caching for given draw-pass.
* TGLLogicalShape - Add a new (optional) argument to DrawHighlight()
specifying kind of outline to use (selected or highlighted). This
allows classes with internal selection to properly render outlines
when sub-parts of an object are both selected and highlighted.
* TGLEventHandler - Proparly handle objects with internal selection /
highlight.
* TGLSelectRecord - Add flag to separate GL-selection for selection
and for highlight. This is really used by record handlers.
* TGLViewer - Add two new signal-emitting functions to properly notify
clients about changes in internal object selection:
virtual void ReMouseOver(TObject *obj, UInt_t state); // *SIGNAL*
virtual void UnMouseOver(TObject *obj, UInt_t state); // *SIGNAL*
tutorials/eve
=============
Add instructions for activation of internal selection in
TEveQuad/BoxSet.

From Alja & Matevz.
Make highlightning configurable on per class basis by introducing a
new virtual function in TGLLogicalShape:
virtual void DrawHighlight(TGLRnrCtx& rnrCtx, const TGLPhysicalShape* pshp) const;
The main use of this functionality will be to support individual
selection of calo towers and potentially other container elements that
support secondary selection.
For now it is used in TEvePolygonSetProjected to highlight only
outline of the polygon.

TGLContext, TGLWidget
---------------------
Add method ClearCurrent() to set current GL context to 0.
TGLLogicalShape
---------------
Change how number of required display-lists per object is handled:
before it was a virtual function, now it is a data member.
Fixes a severe memory leak due wrong number of released display-lists
when called from the destructor, which was calling a virtual function
to determine their number.
Fix accordingly the following classes: TGLSphere, TGLCylinder,
TEveCaloLegoGL and TEveBoxSetGL.

From Matevz:
Major restructuring of GL viewer-scene relationship (Matevz)
===================================================
The main idea was to generalize current GL infrustructure so that the
following features can be done in the future:
1. Full pad rendering via GL including 3D histo/func painters and 2D graphics.
2. Implementation of GL canvas (with independent viewers serving as pads).
3. Multi-view event-visualization front-end.
4. Inclusion of external scenes (non-ROOT-gl) in ROOT viewer.
Rendering of ROOT scenes in external GL frameworks.
Changes on the code level
-------------------------
0. Extend current scene/viewer classes into a 2-level class hierarchy.
New classes TGLViewerBase and TGLSceneBase.
1. Allow scenes to be shared among viewers. View-specific scene-cache
needs to be kept at the viewer side.
2. Viewer now manages a list of scenes. It is possible to put together
a combination of scenes (e.g. one showing geometry, another one tracks
and yet another clusters). Each scene can define its own clipping object.
3. Provide API for fine-grained control over rendered object removal,
creation and update. This allows for efficient scene-updates.
4. Disentangle selection, clipping and other markup objects from
within viewer-scene singleton.
New classes TGLClipSet, TGLManipSet.
6. Disentangle selection management.
7. Separate overlay rendering to allow any number of active GL-GUI
elements (like manipulators are now).
New classes TGLOverlayElement.
8. Trailing white space has been removed in all files.
Restructure low-level interface to OpenGL (Timur)
=========================================
1. Allow sharing GL resources among viewers.
2. Do not bind GL-output (windowed or offscreen) to ROOT GUI.
New classes TGLContext, TGLFormat, TGLWidget.
This oboletes TGLKernel and TVirtualGL classes.

From Matevz Tadel:
1) Implementation of two-level (secondary) selection
Rendering objects can provide a new level of interactivity, for
example a TPointSet3D holding a set of clusters can attach a pointer
to original cluster to each point and receive notifications when a
specified cluster was clicked.
Secondary selection is activated by Control-Left clicking into the
GL window.
2) Improve control over camera-reset behaviour
Allow user to prevent camera reset on scene update and
double-click.
3) Improvements in TPointSet3D(GL)
Detailed ChangeLog
==================
* base/inc/TVirtualViewer3D.h:
Added virtual methods 'void ResetCameras(){}' and 'void
ResetCamerasAfterNextUpdate(){}'.
* gl/inc/TGLScene.h:
* gl/src/TGLScene.cxx:
Implemented two-level selection. It is enabled for next selection
pass by calling ActivateSecSelect().
DoSelect() does not change the selected object but only indicates
which object has been selected by setting new member
'TGLPhysicalShape *fSelectionResult'. Caller (TGLViewer) must call
new method 'void ApplySelection()' to actually change the selected
object to the last selection result.
Changed declaration of selection buffer from being a static varable
within DoSelect() to data-member. This allows post-processing of
selection records needed by two-level selection.
* gl/inc/TGLCamera.h:
* gl/inc/TGLOrthoCamera.h:
* gl/inc/TGLPerspectiveCamera.h:
* gl/src/TGLCamera.cxx:
* gl/src/TGLOrthoCamera.cxx:
* gl/src/TGLPerspectiveCamera.cxx:
Added Bool_t argument with default value to:
virtual void TGLCamera::Setup(const TGLBoundingBox & box, Bool_t
reset=kTRUE) = 0;
By setting it to false one can change camera parameters for new
scene bounding-box without repositioning the camera.
Added 'Bool_t checkSize' argument to OfInterest().
This is relevant for marker-classes which can have small
volume/length but are still visible as they are rendered in
pixel-coordinates. Value of this argument is needed in TGLScene
(DestroyPhysicals) and TGLViewer (AddObject). It is obtained by
calling virtual method TGLLogicalShape::IgnoreSizeForOfInterest().
This method returns false by defalut and is overriden in
TGLPolyMarker and TPointSet3DGL.
* gl/inc/TGLViewer.h:
* gl/src/TGLViewer.cxx:
Added controls for camera-reset behaviour.
Data-members: 'Bool_t fResetCamerasOnUpdate', 'Bool_t
fResetCamerasOnNextUpdate', 'Bool_t fResetCameraOnDoubleClick'.
Methods: 'ResetCameras()', 'ResetCamerasAfterNextUpdate()',
'ResetCurrentCamera()'.
Added an argument to 'void PostSceneBuildSetup(Bool_t resetCameras).
Added Bool_t return-value to RequestSelect(). It returns true if
result of the selection is different then fSelectedPhysical.
Added method ApplySelection() to interface with TGLScene
selection state. This is called from event-handling functions in
TGLViewer.
Added key-binding for 'Home': ResetCurrentCamera().
* gl/inc/TGLSAViewer.h:
* gl/src/TGLSAViewer.cxx:
Added description of new functionality to fgHelpText.
MSVC was complaining about fgHelpText being too long: I split it
into fgHelpText1 and fgHelpText2.
* gl/inc/TGLDrawFlags.h:
* gl/src/TGLDrawFlags.cxx:
Added members 'Bool_t fSelection' and 'Bool_t
fSecSelection' allowing passing of current selection state to
renderers. This is needed to allow different render-paths during
(secondary) selection.
We should consider passing TGLScene* and/or TGLViewer* down to
DirectDraw() of individual renderers.
* gl/src/TGLDrawable.cxx:
In ShouldCache() return false if secondary selection is in progress.
* gl/src/TGLPhysicalShape.cxx:
Handle new members in TGLDrawFlags.
* gl/inc/TGLLogicalShape.h:
* gl/src/TGLLogicalShape.cxx:
Added three new functions:
1) virtual Bool_t SupportsSecondarySelect() const { return kFALSE; }
This is called by TGLScene::DoSelect() to check is object that was
the result of primary selection supports secondary selection.
2) virtual void ProcessSelection(UInt_t* ptr, TGLViewer*, TGLScene*);
It is called back from TGLViewer after successful secondary
selection. As the object that does the rendering is the only one
that actually knows how the object sub-parts were named it has
to interpret the results.
Both of these should be overriden in classes that support
secondary selection, for example see TPointSet3DGL.
3) virtual Bool_t IgnoreSizeForOfInterest() const { return kFALSE; }
Signals to TGLScene and TGLViewer that volume/lenght of this
class' bounding box should not be considered when checking if
objects of this class are of interest to current camera.
* gl/inc/TGLObject.h:
* gl/src/TGLObject.cxx:
Changed second argument of function:
Bool_t SetModelCheckClass(TObject* obj, const Text_t* classname);
to 'TClass* cls'. This is much more efficient.
* g3d/inc/TPointSet3D.h:
* g3d/src/TPointSet3D.cxx:
Added support for per-point designations (one TObject* per point;
via casting it can be set to anything).
New virtual method 'void PointSelected(Int_t n)' that is called
back after successful secondary selection in TGLViewer (via
virtual TGLLogicalShape::ProcessSelection()).
* gl/inc/TPointSet3DGL.h:
* gl/src/TPointSet3DGL.cxx:
Added support for per-point selection. Point-sizes are taken into
account during selection (by modifying the projection
matrix).
Implemented 'virtual Bool_t TGLDrawable::ShouldCache()' to disable
caching when in primary selection (point-size improvements).
Cross-like marker types are now supported to some extent.
Improved structure of rendering code.
Override 'virtual Bool_t TGLLogicalShape::IgnoreSizeForOfInterest()'
to return true.
Multiply TAttMarker::GetMarkerSize() by 5 before applying.
* gl/inc/TGLPolyMarker.h:
Override 'virtual Bool_t TGLLogicalShape::IgnoreSizeForOfInterest()'
to return true.

From Federico Carminati:
"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

Cleanup of shape code:
i) Remaining minodr code from TGLSceneObject moved to TGLLogicalShape or
derv. shape classes.
ii) Remove obsolete TGLSceneObject class.
iii) Move shape classes (TGLFaceSet etc) to own .h/.cxx + now derv. from
TGLogicalShape directly
Plus other minor tidying up.
WARNING!!
if you check-out from CVS, do

From Richard:
First implementation for interactive clipping, using OpenGL clip planes.
Initially we have plane & box - others later. See Help for description.
Known Bugs/Issues:
All in GUI:
i) Edit box takes keyboard focus and does not return to viewer pane when
clicked in. Hence all keys in viewer break - an existing general viewer
problem.
ii) Initial layout does not correctly hide the plane/box properties
panels, or scale for V side scroll bar.
Missing Features:
iii) CSG final pass and/or solid cappings.
iv) Can't rotate the box - need a TGLRotManip class soon.
v) Should be able to show and manipulate plane in similar fashion as
box.
vi) Trans/scale/rotate manipulators should be availible for any selected
object.

Major changes to GL viewer to support:
i) Logical/Physical shape pairings
ii) Level of detail (LOD) scheme (TGLSphere only using at present)
iii) Common display list cache
iv) Scene rebuilds for large geometries
v) Some basic interactivity improvements - draw timeouts, drop low LOD
shapes etc
vi) New camara interactions:
Left Mouse: Rotate
Middle Mouse: Truck (pan parallel to camera film plane)
Right Mouse: Side-side drag dolly/zoom
Double click any button to reset the camera.
The previous pan with arrow keys, and zoom on mouse wheel are still
supported.
Camera interaction is default in viewer. These extra camera modes mean
there are not enough mouse buttons for previous right context/select.
To select / invoke context menu use Shift+Left Button and Shift+Right
Button respectively.
