Move enums away from global namespace:
- EOverlap is now in namespace Rgl;
- EClipType is now in class TGLClip;
- EPosition and EManipType were not used and have been removed.

EGLCoordType and EGLPlotType are left in top-level. In these two enums all
names begin with kGL so there is less chance for collision.

Optimizations based on Druid callgrind dump sent by Manqi.

* TGLBoundingBox:
  Use TGLVertex3[8] instead of std::vector<> for member that always
  has 8 elements. Caused pointless allocations and fragmentation.

* TGLScene:
  In CalcBoundingBox() avoid creating a bounding box temporary in a
  loop over all elements -- use const& instead.

* TGLCamera:
  Fix for changes in TGLBoundingBox.

gl/
===
- Introduce common base class TGLPlot3D for wrappers over plot-painters.
- Move code for plot-painter instantiation from TGLScenePad to into TGLPlot3D.
- TGLAxisPainter - add option to use markup color from the current color-set
  instead of axis/label/title colors from TAttAxis.

eve/
====
- Add class TEvePlot3D - it wraps a TH2/TH3/TF2 object and draws it with
  given option string. TEveTrans can be applied over it - so the plot
  can be positioned/scaled to fit into a more complex scene.
- There are still problems with usage of depth-buffer in plot-painters so
  the plots overlay each other in somewhat random fashion.
- See tutorials/eve/test_glplot.C.

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 Richard:
Further GL / LOD performance improvements:

i) Shape can indicate LOD support by axis. For tubes TGLCylinder only X+
Y supported. Calc LOD hint based on larger projection of Z faces of
bounding box, avoiding excessive LOD for long tubes.

ii) Only test time limited draws every 50 objects to avoid excessive
timing costs.

From Richard:
Various updates to cameras:

i) Larger range/sensitivities
ii) Better auto-framing for ortho cameras
iii) Better lighting - especially for ortho views
iv) Some more debug aids for scene center, origin and light positions -
enabled in debug mode (d key)

From Richard:
i) Add rotation manipulator.
ii) Allow direct manipulation of clipping plane - rotate/translate.
Cannot scale - makes no sense.

Note:

iii) Rotation interaction requires some improvement - difficult when
ring is almost parallel with eye line of camera.
iv) Still need to extend for all selected objects - requires some
internal rearrangement of TGLScene/TGLViewer

From Richard:
First implementation for interactive clipping, using OpenGL clip planes.
Initially we have plane & box - others later. See Help for description.

Known Bugs/Issues:

All in GUI:

i) Edit box takes keyboard focus and does not return to viewer pane when
clicked in. Hence all keys in viewer break - an existing general viewer
problem.
ii) Initial layout does not correctly hide the plane/box properties
panels, or scale for V side scroll bar.

Missing Features:

iii) CSG final pass and/or solid cappings.
iv) Can't rotate the box - need a TGLRotManip class soon.
v) Should be able to show and manipulate plane in similar fashion as
box.
vi) Trans/scale/rotate manipulators should be availible for any selected
object.

Futher viewer tuning:

ii) Add a cheap sphere/sphere test first in TGLBoundingBox::Overlap
iii) Only do scene rebuilds after a full quality draw has completed.

From Richard:
Improvements to camera and other GL viewer components to:

i) Avoid unrequired rebuilds.
ii) Improve near/far clip plane calculations - set using current
projected scene limits. Reduces depth buffer precision problems - seen
particularly on MESA software GL.
iii) Improve bounding box overlap tests.
iv) Tidy some vector/vertex code.

From Richard Maunder
Fix for incorrect assert when creating BB with single point
(TPolyMarker) - found with overlap case. We can live with this - create
zero volume BB which camera always accepts as special case.

From Richard
Update to GL viewer to:

i) Retain modifications/section of physical shapes across scene
rebuilds.
ii) Be a bit smarter about rebuilds:

        Detect if all physicals accepted into scene - never need to rebuild in
these cases.
        Only destroy physicals no longer of interest to camera.

Imporves times a bit - more work on this required to remove stalls in
viewer interaction.

From Richard Maunder:
Fixes for camera limits - greater ranges +

Right Mouse: Dolly Camera (Move In/Out) with side/side motion (as
before). Also j/k keys control.

Mouse Wheel: Zoom Camera - adjust field of view of 'lens'. As expected
this can introduce noticable distortion at wide angles.

Combination of two gives a very large 'zoom' range for the camera
sufficient for current detectors.

Additionally modifiers adjusts the sensitvity of the interactions,
making easier to tune in on a certain part:

Shift:          x 10
Ctrl:           x 0.1
Shift+Ctrl:     x 0.01

NB Modifier must go down after mouse button for shift to avoid
[Under Win32 the modifiers do not work with mouse wheel (Zoom) as
TGEvent does not contain them for some reason. Will log a bug for this
to be looked into]

Also:

i) Added 'debug' mode for viewer (toggle with 'd' key) which draws out
camera interest, frustum basis, scene boxes etc in various colors. In
debug mode rebuilds only done when forced with space key strike.

ii) Fixes lost objects in some scene rebuilds.

From Richard maunder:
Draw Sorting: Draw objects in order of decreasing BBox size - makes
dropouts on time termianted draws less intrusive - especially on slow
cards/software only. Reduced interactive drawtime to 100msec (from
300msec).

Added scene locking + more tracing to assist with debugging -
particularly under win32 mutli-thread.

From Richard Maunder:
Major changes to GL viewer to support:

i) Logical/Physical shape pairings
ii) Level of detail (LOD) scheme (TGLSphere only using at present)
iii) Common display list cache
iv) Scene rebuilds for large geometries
v) Some basic interactivity improvements - draw timeouts, drop low LOD
shapes etc
vi) New camara interactions:

Left Mouse: Rotate
Middle Mouse: Truck (pan parallel to camera film plane)
Right Mouse: Side-side drag dolly/zoom
Double click any button to reset the camera.

The previous pan with arrow keys, and zoom on mouse wheel are still
supported.

Camera interaction is default in viewer. These extra camera modes mean
there are not enough mouse buttons for previous right context/select.
To select / invoke context menu use Shift+Left Button and Shift+Right
Button respectively.
