TEveManager
-----------
1. Implement Load/SaveVizDB()
2. Add bool members controlling behaviour of VizDB during loading, in
particular whether to replace existing entries and update connected clients.

TEveElement
-----------
1. Implement top-level SaveVizParams() and virtual WriteVizParams()
that is called throughout the element class-hierarchy.
2. Add the following methods that can be called from the context menu:
   - void VizDB_Apply(const char* tag);
   - void VizDB_Reapply();
   - void VizDB_UpdateModel(Bool_t update=kTRUE);
   - void VizDB_Insert(const char* tag, Bool_t replace=kTRUE, Bool_t update=kTRUE);

Other
-----
Virtual WriteVizParams() implemented for the following classes:
TEvePointSet, TEveLine, TEveTrack, TEveTrackList and
TEveStraightLineSet.

outline-pass of the highlight.

TGLObject
---------
Disable use of display-lists for multi-colored objects only in the
outline pass of the highlight.

TGLPhysicalShape

strangely enough Wndows does not support %p, use good old 0x%lx.

=============

Break render into two pieces to give sub-classes more control over
rendering procedure.


TGLViewer
=========

Render axes/guides before selected/highlighte objects so that
depth-test can be honoured (if requested).


git-svn-id: http://root.cern.ch/svn/root/trunk@24316 27541ba8-7e3a-0410-8455-c3a389f83636

===========

Keep projections in an array and reuse them when changing
projection-types. This allows parameters set by users to be kept for
each projection type separately (only center is controlled by manager).


TEveProjections
===============

Introduce pre-scaling of projected objects: users can specify
different scaling factors for regions of projected coordinate space.
Fish-eye distortion is applied afterwards.

Demonstrated by the new tutorial 'projection_test_prescale.C'.


git-svn-id: http://root.cern.ch/svn/root/trunk@24314 27541ba8-7e3a-0410-8455-c3a389f83636

git-svn-id: http://root.cern.ch/svn/root/trunk@24313 27541ba8-7e3a-0410-8455-c3a389f83636

on 64bits, too.

TEveCalo2DGL, TEveCalo3DGL:
Assert palette in DirectDraw().

TEveCaloData:
Add DataChanged() to notify all referenced calo-viz objects to refresh
cell id cache, update eta, phi limits and palette.

TEveCaloVizEditor:
Set eta, phi limits for TEveGValuators in SetModel().


git-svn-id: http://root.cern.ch/svn/root/trunk@24291 27541ba8-7e3a-0410-8455-c3a389f83636

Move build of TEveCaloData::CellId_t cache from render classes to the base
classes. Rename fCache to fCellIdCache.

TEveCaloData:
Inherit from TEveRefBackPtr. Add function InvalidateUsersCache() to
make correct update on all calo references when changing threshold and

CaloClasses:
Rename ResetCache() to DeleteCache(). Add get/set methods for
slice-color and slice-threshold.

----------

Rename function for adding cones to AddCone() and reorder the
parameters to a more logical order.


git-svn-id: http://root.cern.ch/svn/root/trunk@24215 27541ba8-7e3a-0410-8455-c3a389f83636

-----------------------------------------

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.

TEveBoxSet classes:
Introduce new structure to draw cone set. 

tutorials/eve/boxset_test.C
Add function cone_test() to test cone set.

TEveDigitSet, TEveQuadSet:
Fix member in ERenderMode_e, to draw properly in wire-frame rendering mode.


git-svn-id: http://root.cern.ch/svn/root/trunk@24210 27541ba8-7e3a-0410-8455-c3a389f83636

  Fix creation of TGLWidget so that it also works with software
  rendering where few visuals are available.
  This means that we have to break TGLWidget construction into three
  phases (required for software rendering on X11):
  1. find appropriate visual and create window;
  2. create widget using the above window;
  3. create gl-context binding them together.
  To avoid unexpected behaviour the construction is now done via
  static constructor 'TGLWidget* TGLWidget::Create()' and the
  actual constructor has been made protected.

- TGLEmbeddedViewer, TGLSAViewer
  Use new TGLWidget construction syntax.

- TGLPShapeObjEditor
  Use new TGLWidget construction syntax.
  Fix rendering and update of color-sphere.

  Use tower-size as default representation for projected view.

- TEveGeoNode
  Use default constructor of TGeoManager so that it does not attempt to
  register itselg to gROOT which might not be initialized yet.
  (Thanks to Bertrand for tracing this down.)

Remove TGLWidgetContainer class and change inheritance of
TGLWidget as following:
before: class TGLWidget : public TGCanvas, public TGLPaintDevice
now:    class TGLWidget : public TGFrame,  public TGLPaintDevice
 
Now TGFrame base class is used directly to tie with the GL Context,
instead of creating an external window and registering it in TVirtualX
window list.

Change GetCellData() to const.

TEveCalo:
Set threshold in SetData().

TEveCaloLegoGL:
Fix tick-marks and change rendering order of cells and plane.

TGLCamera:

Coordinate-system conversion functions ViewportDeltaToWorld(),
ViewportToWorld() and WorldToViewport now take an optional argument
specifying model-view matrix to be used in calculation.


git-svn-id: http://root.cern.ch/svn/root/trunk@24158 27541ba8-7e3a-0410-8455-c3a389f83636

  Added member 'Bool_t fImportEmpty' - this forces the projection manager
  to also import sub-trees without any projectable elements.
  Useful if one expects a completely parallel element structure in
  projected replica.

- TEveSelection:
  Added method 'void RemoveImpliedSelected(TEveElement* el)' needed for
  deregistration of implied-selected elements during their destruction.

- TEveManager:
  - In PreDeleteElement() check if the element is implied selected or
    highlighted and deregister it from there.
  - In function InsertVizDBEntry():
    a) added argument 'Bool_t update';
    b) when replacing the model-element copy its children to the new
       model and optionally update their viz-params.

- TEveElement:
  - Add methods to simplify propagation of visualization-parameters
    between model-elements and their clients
  - Add members 'Int_t fParentIgnoreCnt, fTopItemCnt' that allow
    better tracking of references in view of automatic destruction.
  - Consolidate Has/Num|Children/Parents() methods.

- TEveGeoNode:
  Use TEveElement::HasChildren() instead of checking container size.

  scaling.

  Add utility functions to check if a phi interval lies within or
  overlaps with another interval taking into account the U(1)
  wrap-around.

- TGLCamera
  Fix AdjustAndClampVal() fix poorly implementd logarithmic scaling of
  the value step.

- TGLOrthoCamera
  Add get/set methods for fZoomMin/Max.

  Add member 'TEveElement *fVizModel' that points to VizDB entry used
  for determination of element's visual properties.
  When setting the VizModel add it as a child to the model-element.
  This will allow for two-way communication between client and model
  elements.

- TEveManager
  When adding a model-element into VizDB increase its deny-destroy
  count. Use Destroy() not direct delete when removing it.

- TEvePolygonSetProjected
  - Override TEveElement::SetMainColor() so that we can keep line and
    fill colors in sync if this is desired.
  - Remove SetLine/FillColor(Pixel_t).

- TEveGeoNode
  Add some info and warning messages for unexpected conditions (which
  I now suspect might actually happen in some rare cases).
