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 & Alja

	* base/inc/TVirtualViewer3D.h:
	Add function virtual void ObjectPaint(TObject*, Option_t*).


/**************************************************************************/

	* ged/src/TGedEditor.cxx:
	When adding top-level TGFrame for the extra tabs specify layout
	hints with kLHintsExpandX.


/**************************************************************************/

	* gl/inc/TGLScenePad.h:
	* gl/src/TGLScenePad.cxx:
	Implement virtual TVirtualViewer3D::ObjectPaint().

	* gl/src/TGLCamera.cxx:
	* gl/inc/TGLCamera.h:	
	* gl/src/TGLPerspectiveCamera.cxx:
	* gl/inc/TGLPerspectiveCamera.h:	
	* gl/src/TGLOrthoCamera.cxx:
	* gl/inc/TGLOrthoCamera.h:
	Introduce two transformation matrices to clearly define movement
	of camera around the center point. The first transformation matrix
	fCamBase defines the coordinate system placed at the camera center
	point with camera up-vector as the third base vector. The second
	transformation matrix fCamTrans defines the camera transformation
	relative to fCamBase.

        Implement a common Truck(), Rotate() and Dolly() function for
	orthographic and perspective camera.

	Implement an option to define camera center point
	externally. Center can also be determined via picking.

	* gl/src/TGLUtil.cxx:
	* gl/inc/TGLUtil.h:
	TGLMatrix: add new functions to get/set the base vectors
	directly.

	TGLUtil: add member UInt_t fgDefaultDrawQuality.

	TGLRect: bugfix in Diagonal(), integer calculation overflowed.

	* gl/src/TGLViewer.cxx:
	* gl/inc/TGLViewer.h:
	Make interface to draw camera center point.
	Add option to disable/enable depth test when drawing axis guides. 

	* gl/src/TGLViewerEditor.cxx:
	* gl/inc/TGLViewerEditor.h:
	Add GUI to manipulate camera center and to disable/enable depth
	test when drawing axis guides.

	* gl/src/TGLClipSetEditor.cxx:
	Change layout of labeled number entries.

	* gl/src/TGLLightSet.cxx:
	Fix positioning of front light. White-space consolidation.

	* gl/src/TGLLightSetEditor.cxx:
	* gl/inc/TGLLightSetEditor.h:
        Put GUI for the 6 lights in two columns.


/**************************************************************************/

	* tutorials/gl/glViewerExercise.C:
	Follow-up on changes in TGLCamera. Enable rotation on
	orthographic camera.

	* tutorials/gl/glViewerLOD.C:
	Workourond for cint bug with switch statements.

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.
