* TGLFormat, TGLWidget
  Add handling of multi-sampling formats for GLX.
  WGL implementation is still missing.
  The value is taken from TEnv "OpenGL.Framebuffer.Multisample".

* TGLViewerBase
  Use TGLCapabilityEnabler for switching on bleniding.

* TGLViewer
  Remove flas fInitGL and associated functions.
  Set sane GL state on every Draw().
  Consolidate image extraction from frame-buffers.

* TGLEmbeddedViewer, TGLSAViewer
  Remove calls to ResetInitGL().

* TGLRnrCtx
  Remove fGrabBuffer and fGrabbedImage members, only keep fGrabImage flag.
  All the rest is handled internally in TGLViewer now.

* TGLFBO
  Add support for multi-sampling FBOs.

Add support for stereo rendering. This requires a graphics card that
supports quad-buffering and shutter glasses.

The standard drawing code is unchanged.

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 Matev and Timur:
Timur:
1. Allow unique identification of shared GL contexts via
TGLContextIdentity class.

Matevz:
1. Improved overlay selection handling.
2. Perform GL context check before rendering, possibly invalidating
   registered display-lists.
3. Minimize updates for window expose and resize events.

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.
