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.

-Add include "TROOT.h" in all implementation files that were assuming
that TROOT was included via TClass.h
-In TClass.h:
--Remove the include of TROOT.h
--add the following static member
static IdMap_t *fgIdMap; //Map from typeid to TClass pointer
--add the following functions:
static void AddClass(TClass *cl);
static void RemoveClass(TClass *cl);
--Replace the inline definitions of GetClass functions by
template <typename T> TClass* GetClass( T** /* dummy */) { return GetClass((T*)0); }
template <typename T> TClass* GetClass(const T** /* dummy */) { return GetClass((T*)0); }
-In TClass.cxx:
--Instead of forwarding the calls to gROOT->GetClass, move the code
originally in TROOT in the TClass::GetClass functions
--Move class TMapTypeToTClass from TROOT to TClass.

Reduce direct dependencies on TClass.h, TROOT.h and TStreamerInfo.h.
Warning: This means that some file that relied on the indirect
inclusion of these header file might now fail to compile with
an error message mention that gROOT is no known or that TClass,
TROOT or TStreamerInfo is incompletely defined. Simply add the
proper include directive.

From Richard Maunder:
Changes to viewer infrastructure (TBuffer3D,TVirtualViewer3D) to
support:
i) Proper shape specific (sphere, tube, etc) descriptions in TBuffer3D
derived classes - c.f. abuse of raw tesselation blocks before.
ii) On demand filling of buffer sections as required by viewer.
iii) Support for local/master frame shapes descriptions & child object
rejection.
iv) Template/placed shapes ids - enabling viewer to detect/receive
common shapes once and just obtain the new position and id of the
duplicate.
Cleans up all producer (g3d/geom) code so no longer has an viewer
specific knowledge - Paint() methods replaced with
GetBuffer3D/FillBuffer3D methods which complete requested sections of
the buffer.
All viewer specific code now sits on the viewer implementation side of
TVirtualViewer3D. Added a TViewer3DPad class for performing the 3D draws
into pad. In future this should be merged with TView/TView3D possibly.
TBuffer3D is now stripped of functional code (aside from memory
management) and various viewer passback options there previously.
Enforced one way passing a const & to viewer.
Buffers (various types) are held as single static inside producer
function e.g. TGeoShape::GetBuffer3D (c.f. single generic buffer type
fetched from pad previously).
For g3d and geom shapes the top level geometry painter (TNode /
TGeoPainter) controlls painting process, requesting shapes to fill
buffer and passing to 3D viewer.
Exceptions are g3d's TPolyLine3D, TPolyMarker3D & TMarker3DBox. These
are 'standalone' shapes - no controlling 'painter' object. They still
implement Paint(), fill buffer and add to viewer directly.
3D viewer still held / created by pad - and pad has it's own viewer
object (TViewer3DPad).
NOTE:
1. Current scheme supports one 3D viewer only - pad, x3d or OpenGL. This
means that pad goes blank when x3d/OGL is spawned, and is updated again
when it is closed. To be revisited - need to support multiple viewers,
of multiple types - which implies explicit naming or pad controlling
enumeration.
2. OGL viewer now responds correct to modifications in pad, without
having to be reinvoked (as previously). x3d is still decoupled (as
previously) so does not rebuild - too difficult to get working.

From Olivier, Timur Pocheptsov , Andrei Gheata and Rene
Mega patch to introduce the new 3-d interface (to be described later).
The new interface has been tested with both X3D and OpenGL under Linux.
Being tested under Windows.
Note that several changes are expected in these classes (OpenGL in particular)
in the coming days.
