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.

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

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:

Improve clipping in GL viewer. Now show back (inner) faces when clipped,
with two sided lighting. Not as good as proper CSG op to cap clipped
solids - but looks better than them being invisible.

Also seems to improve performance which is suprising .....

From Richard:
 Second part of general tidy for coding conventions violations -
mainly commenting. Code under my name should be clear now.

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.

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.
