* 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.

Add support for storing composite-shapes as shape extracts.

TEveGeoPolyShape
----------------
New sub-class of TGeoBBox that can hold arbitrary triangulation as
produced by CSG operations. This class is for visualization only.

TEveGeoNode
-----------
Add logic for composite-shape extraction during export of a shape
extract.
Add static data member fgCSGExportNSeg to control level of detail for
CSG operations during export.

tutorials/eve/advanced
----------------------
Added tutorials showing how to use this advanced functionality.

TGLFaceSet - add some getters to extract the result of CSG operations.

Changes for marking of top-level objects in GL window.
- TGLLogicalShape: move DirectDraw() from protected to public.
- Implement color-locking for object rendering.
- Wrap all calls to glColor() to go via TGLUtil::Color().

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

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.
