Implement highlighting using the stencil buffer.
Produces minor artefacts when more than one clipping plane is active but
performs much better for all other cases.

Generalize selection handling for scenes:
- By adding TGLLogicalShape* to TGLSelectRecord the scene sub-classes now have
the ability to lie pretty badly to TGLEventHandler about what actually got
selected and thus achieve great flexibility in managment of scenesobject
collections that do not conform to standard ROOT / EVE / TPad paradigms.
Generalize rendering order and selection/highlight handling.
- Rendering order of opaque/transparent and non-selected/selected objects can
be set via TGLRnrCtx::RenderOrder(), enum ERenderOrder.
- Selection of transparent objects via TGLRnrCtx::SelectTransparents(), enum
ESelectabilityOfTransparents.
- Rendering of highlight halo can be controlled via:
- TGLRnrCtx::SetHighlightDepthRangeOffset(Float_t);
- TGLRnrCtx::SetHighlightedObjectDepthRangeOffset(Float_t);
This should really be rewritten either to use stencil buffer or shaders.

From Alja.
GLRnrCtx:
Add possibility for automatic font scaling.
TGLFontManager:
In RegisterFont() check if font state has changed and check valid font size. Before,
this checks were done in the renders.
render classes:
Use optionally scaled or non-scaled fonts. Remove checks for FTGL fonts,
since they are now done in TGLFontManager:RegisterFont().

Add support for frame-buffer objects (FBO).
This allows for offscreen rendering into separately instantiaded
frame-buffer. Useful for saving of images whan the GL window is now
visible or for rendering into textures.
Requires OpenGL-1.5 (detected at run-time with GLEW).
In TGLViewer add new function
Bool_t SavePictureUsingFBO(const TString &fileName, Int_t w, Int_t h);
that allows saving of an image with any resolution supported by the
local GL implementation (8192 pixels on my desktop).

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).

TGLViewer - create two color-sets by default - for light and dark
background. These can be switched with the 'e' key now.
TGLScene - decrease polgon-offset for outline-mode fill-pass from (1,
1) to (0.5, 0.5) which is sufficient.
Use/support color-set functionality in other modified classes.

color-sets for a given viewer.
TGLViewerEditor - Disable backgound-color widget when the viewer uses
global color-set.

TGLObject and subclasses
-----------------------------------------
Introduce new member 'Bool_t TGLObject::fMultiColor' that specifies
whether the class uses multiple colors for its rendering. This
information is important when drawing highlight or outlines around
objects as display-lists can not be used if color-state changes are
stored in them.
With this modification most of the logick for
virtual Bool_t TGLLogicalShape::ShouldDLCache(...)
can be implemented in TGLObject version.
Most of the GL-rendering classes have been fixed to properly set the
fMultiColor state and rely on the TGLObject::ShouldDLCache().
TGLPhysicalShape
----------------
Use TGLLogicalShape::Draw() instead of DirectDraw() when drawing
highlights to allow usage of display-lists for classes that do not use
multiple colors.
TGLUtil
-------
Decrease the default draw-quality for DrawLine/Cylinder/Sphere/Disk to
10. With software rendering the previous value of 60 caused very low
refresh rates.
Introduce two inner classes TDrawQualityModifier and
TDrawQualityScaler allowing easy/safe modification of draw-quality for
the above functions.
Introduce inner class TColorLocker allowing easy/safe modification of
color-lock state.

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.
