Add support for mac retina display. In practice it means we need to support a
scaled coordinate system within GL windows. We use full resolution in GL while
GUI and window system work in points that are 2x2 pixels.

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.

Bugfix: scene guides were drawn during object selection and there was a
missing check for zero-size name-stack size. So, hovering over an axis or
camera center sphere resulted in a crash.

* TGLSelectBuffer - return name-stack size from Set() method.
* TGLViewerBase - check name-stack size before accessing elements.
* TGLViewer - do not draw non-scene objects in rendering for selection.

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.

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.

* TGLFormat, TGLWidget
  Add handling of multi-sampling formats for GLX.
  WGL implementation is still missing.
  The value is taken from TEnv "OpenGL.Framebuffer.Multisample".

* TGLViewerBase
  Use TGLCapabilityEnabler for switching on bleniding.

* TGLViewer
  Remove flas fInitGL and associated functions.
  Set sane GL state on every Draw().
  Consolidate image extraction from frame-buffers.

* TGLEmbeddedViewer, TGLSAViewer
  Remove calls to ResetInitGL().

* TGLRnrCtx
  Remove fGrabBuffer and fGrabbedImage members, only keep fGrabImage flag.
  All the rest is handled internally in TGLViewer now.

* TGLFBO
  Add support for multi-sampling FBOs.

New Revision: 33431

URL: http://root.cern.ch/viewvc?rev=33431&root=root&view=rev
Log:
Add full support for handling of projected tracks in topologically non-trivial
projections. Use the following setters in TEveTrackPropagator:
   void   SetProjTrackBreaking(UChar_t x);
   void   SetRnrPTBMarkers(Bool_t x);
   TMarker& RefPTBAtt() { return fPTBAtt; }
to tune the behaviour. The following modes are supported:
   enum EProjTrackBreaking_e {
     kPTB_Break,            // break tracks
     kPTB_UseFirstPointPos, // use first track-point half-space
     kPTB_UseLastPointPos   // use last track-point half-space
   };

SetRnrPTBMarkers(Bool_t x) allows to enable drawing of a marker with
attributes RefPTBAtt() at break-points.

Introduce virtual function:
  void TGLViewerBase::SetupClipObject()
that is called half-way through the TGLViewer::PreRender() -- when
overall bounding box is known but the individual scene visibility has
not been determined yet. Thus scene visibility can be properly
determined if the clipping object changes due to a large change in
overall bounding box.
This is overriden in TGLViewer where all clipping objects (plane and
box) need to be modified.

Move auto-clip-update flag from TGLViewer to TGLClipSet so that the
TGLClipSetEditor can modify it.

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).

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.

redrawn due to internal state changes of scenes.
AddScene() now returns TGLSceneInfo* holding viewer-specific
information of the newly created scene.

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 Matev and Timur:
Timur:
1. Allow unique identification of shared GL contexts via
TGLContextIdentity class.

Matevz:
1. Improved overlay selection handling.
2. Perform GL context check before rendering, possibly invalidating
   registered display-lists.
3. Minimize updates for window expose and resize events.

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.
