Rewrite highlight rendering so that the stencil-control logic lives on the
TGLScene level, within new function TGLScene::RenderHighlight(). A set of new
functions called RenderXXXForHighligt() was introduced in TGLViewer/Scene.
This works around the problems with stencil buffer
coherency during multi-pass rendering with multiple clipping planes.
Some tweaking was necessary in TEve-GL classes that implement specialized
DrawHighlight() virtual from TGLLogicalShape.

Add to TGLViewerBase the following function:
TGLLogicalShape* FindLogicalInScenes(TObject* id);
that allows overlay elements to get GL rendering objects.

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).

Merge revs 25435:25641 from the fireworks branch.
Many improvements in text and axis rendering for orthographic views,
for axes in non-linear projections and for the dedicated lego view.
TGLSceneBase
------------
Add data-member 'Bool_t fSelectable' with get/set methods.
If this is set to false, the scene is not rendered during selection
thus preventing any of its elements to be selected.
TGLViewerBase
-------------
In PreRender() honour the selectable state of a scene when selecting
which scenes to include in rendering.
TGLSAViewer
-----------
Remove extra border introduced by usage of kSunkenFrame.
TGLEmbeddedViewer
-----------------
Add optional argument 'Int_t border' to the constructor.

From Alja, Bertrand and Matevz - merged branches/dev/fireworks 22550:23082.
Major changes imported by this merge are:
gl/
====
- reorganization of scene rendering in TGLViewer - render opaque
objects from all scenes first, then all transparent ones;
- improve saving of images from the GL-viewer so that the dialog boxes
and other windows do not result in black areas on the saved image;
- improved management of FTGL fonts accross GL contexts.
eve/
====
- new classes for visualization of calorimeter data in lego mode;
- allow fixed scale beyond given radius for fish-eye projections.

In TGLScene/TGLViewer add two timeouts for high-quality and
low-quality (during rotation etc) scene rendering. Expose both time
limits via TGLViewerEditor.
In TGLCamera::OfInterest() remove redundant test for physical-shape
bbox volume and optimize the remaining bbox diagonal length test.
Remove blanks from the eols.

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.
