4.7.0

1. Implement simple TTree::Draw over single leaf (#80).
   
   Support basic types, fixed-size arrays and several vector types
2. Display of TEveTrack(s) and TEvePointSet(s) over drawn geometry (drag and drop).
   
   Also browsing, toggling, highlight of tracks and hits are done.
3. Let set default geo colors as TGeoManager::DefaultColors() does
4. Let use original ROOT macros to configure visibility of geometry volumes.
   
   One can set default colors or colors/transparency for selected volumes.
   
   Also volume, selected for drawing in the macro, will be used in the JSROOT.
   
   Example: &file=files/alice2.root&item=Geometry;1&opt=macro:macros/geomAlice.C
5. Support drawing of TH2Poly class with 'col' and 'lego' options
6. Implement 'CONT', 'ARR' and 'SURF' draw options for TH2 class
7. Support basic drawing of TPolyLine class
8. Interactive axis zooming in 3D with mouse, very much like to 2D
9. Zooming and tool buttons via keyboards

4.6.0

1. Improvements in TGeo drawings
   • support of large (~10M volumes) models, only most significant volumes are shown
   • one could activate several clip planes (only with WebGL)
   • interaction with object browser to change visibility flags or focus on selected volume
   • support of floating browser for TGeo objects
   • intensive use of HTML Worker to offload computation tasks and keep interactivity
   • enable more details when changing camera position/zoom
   • better and faster build of composite shapes
2. Improvements in histograms 3D drawing
   • all lego options: lego1..lego4, combined with 'fb', 'bb', '0' or 'z'
   • support axis labels on lego plots
   • support lego plots for TH1
3. Improvements in all 3D graphics
   • upgrade three.js to r79
   • use of THREE.BufferGeometry for all components
   • significant (up to factor 10) performance improvement
4. Implement box and hbox draw options for TH1 class
5. Implement drawing of axes ticks on opposite side (when fTickx/y specified)
6. Preliminary support of candle plot (many options to be implemented)
7. Update draw attributes (fill/line/position) when monitor objects
