From Timur.
Draw all plots so that they are contained within a unit-box centered
at the origin.
This is the first step towards allowing mixing of plots with other
scene elements.

From Matevz:
1. TGLViewer performs internal loop on pad-primitives.
2. Timur: generalization of gl-plot-painters to allow external access.
3. Support usage of gl-plot-painters in gl-viewer.
4. Provide a default gl-sharing context for resource optimization.

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.

- From Timur:
First implementation of the 3D iso surfaces with GL. Example:
{
gStyle->SetCanvasPreferGL(true);
TCanvas * canvas = new TCanvas("C","C",600,600);
ntuple->Draw("px:py:pz>>h3");
h3->SetContour(5);
h3->Draw("gliso");
}
(Still needs improvments)

- From Timur:
1. TGLParametricEquation. New class to define parametric surface. It can be
defined by a) three equation in a "string form" (mathematical expression,
the same as TF2) and as a pointer to function.
2. TGLParametricPlot. Painter to draw parametric surface. It has most of
features other gl-painters have - box cut, zooming etc. + 21 color
"schemes": you can change the color of surface (which is under cursor)
by pressing 's' or 'S' - the same as TGLTF3Painter + wireframe mode ('w' or
'W' key - temporary solution).

- From Timur:
Box cut added for TF3, surface and box painters. To activate it - press c. To
move this box - select it (it's highligted when selected), press shift and left
mouse button and move it. Box can move along one of axes - X/Y/Z. Direction is
shown as a red line. To select direction - press X or Y or Z keys.

From Timur:
New classes:
1.
TGLBoxPainter - implements "glbox" option for TH3, shows bin contents as
boxes, which sizes are proportional to bin content. "glbox1" is the same,
as previous, but with spheres instead of boxes. Slices (XOY/YOZ/XOZ)
are now drawn as sets of rectangles.
2.
TGLLegoPainter. Changes: removed all stuff, which works with gl
projections, modelview transformations, textures, etc.
3.
TGLPlotPainter. Added common parts of different painters:
generic Paint function, PlotSelected, etc.
4.
TGLOrthoCamera. Added operations, required by gl hist painters.
5.
TGLHistPainter. Class completely changed (previously known as
TGLPadHistPainter).
6.
TGLPlotBox. New class, draws back box for different kinds of plots,
highlights planes which are under cursor, makes some sizes calculations
(converts 3d into 2d coords) etc.
7.
TGLSurfacePainter. New class, for different surf options.
Supports cartesian, polar, cylindrical and spherical coords.
Slices (XOY, YOZ, XOZ), projections.
8.
TGLTF3. New class, draws TF3. No slices available now.
9.
TGLUtil. Added new auxilary classes
TGLLevelPalette, TGL2DArray, functions, required by different plot
painters,
TGLEnableGuard and TGLDisableGuard removed from RootGL namespace into
global namespace.
