* TGLFaceSet
Add static flag fgEnforceTriangles and function 'void EnforceTriangles()'.
When fgEnforceTriangles is set, all tesselations will be automatically
converted into triangle-only meshes.
This is needed to export TGeo shapes and CSG meshes to external
triangle-mesh libraries that can not handle arbitrary polygons.
* TGLUtil
White-space.
* csgdemo.C
Use the same number of segments for display and export.

From Bertrand.
Avoid potential crash on Windows when trying to access the elements of
an empty std::vector (e.g. Double_t *pnts = &fVertices[0])
This happens if a an empty TBuffer3D (with zero polygons) is passed to GL.

TGLUtil::GetDrawTesselatorXyzz
------------------------------
Four different tesselators are needed depending on what type
(float/double) and size (3d/4d) of data is being fed into them.
Thanks to Bertrand for spotting and localizing this problem.
TGLFaceSet
TEvePolygonSetProjectedGL
-------------------------
Use new functions for obtaining the tesselators.

Move common code for creation of GLUtesselator object from TGLFaceSet
and TEvePolygonSetProjectedGL to TGLUtil.
Use GLUtesselator instead of deprecated typedef GLUtriangulatorObj.

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.
