Add support for control over viewer-global point-size and line-width
scaling. Additionally, allow wireforame and outline line widths to be
specified separately (on viewer / scene / scene-info level).

This will allow for scaling of pixel-based objects (lines and points) when
saving of screenshots with very high resolution is
implemented.

Basic support is impemented across TGLViewer, TGLScene, TGLRnrCtx and
TGLUtil.

Classes that used glPointSize and glLineWidth were modified to call
corresponding static function in TGLUtil class.

Controls were added to TGLViewerEditor (under Style tab).

TGLSceneBase, TGLScene, TGLSceneInfo
	Move 'Bool_t fUpdateTimeouted' from TGLScene to TGLSceneInfo.
	Remove	'Bool_t fForceUpdateSI from TGLSceneBase.
	This was potentialy wrong ... if a scene was put into several
	viewers.

TGLEventHandler
	When scrolling via mouse-wheel or resizing the viewing area
	call redraw via timer to group several events in a sequence
	into a single redraw.
	Avoid selection in handle-motion and in timer callback when a
	redraw is already pending.

TGLViewer
	Do not draw when viewing area's width or hight <= 1.

TGLWidget
	Pass configure-notify event to TGFrame as well.

alice_esd_split.C
	Do not resize to almost-full-screen as it doesn't work with
	multi-screen displays (can pass optional argument to enforce
	it).

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:
Added member Bool_t fActive that allows a viewer to bypass rendering
of the referenced scene without losing the internal data.

From Matevz:
Move interest draw-list into scene-info as it is
view-dependent. Provide additional checks and hooks during
scene-prerender for automatic reinitialization of these structures.

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.
