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.

From Timur Pocheptsov:

-TGLPixmap - removed and replaced by TGLViewer (most of the TGLViewer
    functionality is available in pad now);
-TGLHistPainter - zooming/panning added for legoes/surfaces;
-TGLViewerEditor - TGLViewer's editor for pad (lights/clipping/guides
    manipulation).

-TRootCanvas :
  minor changes to support mouse wheel event in gl viewer in a pad

-TCanvas :
  a)changes to process keyboard events correctly
  b)changes to process mouse will events

-TVirtualViewer3D :
  changes in interface for TGLManager (win32 implementation of TGLManager
  requires some functions and cannot be dependant from TGLViewer)

-Added class TVirtualGLManipulator - base for TGLManip - again, required
 mostly by TGWin32GL.

From Timur:
In view of the coming GL-in-TPad new features, I have changes in
several modules and want to add them step by step. This is the first
update, these classes are auxiliary stuff. I'm planning to add other stuff
tomorrow (and modification in pad and canvas, which will enable
gl-in-pad).

TGLManager is a base abstract class, responsible for
window creation, gl-context/glpixmap and context creation,
manipulation with gl-context and gl-pixmap.

TGWin32GLManager - concrete implementation for Win32
TGX11GLManager - concrete implementation for X11.

change name of TVirtualGLimp to TVirtualGLImp to be consistent with
existing naming conventions.

From Valeriy Onuchin and Timur  Pocheptsov
New OpenGL interface should be now operational on Linux and Windows
