   • let resize frames and paves in all eight directions
   • support lines, boxes and arbitrary text positions in TPaveText

6. New in geometry viewer:

5.2.1

1. Fix - correctly handle new TF1 parameter coding convention (#132)
2. Fix - Check if pad name can be used as element id (#133)
3. Fix - adjust title position for vertical axis with fTitleOffset==0

5.2.0

1. Basic JSROOT functionality can be used in Node.js:
   var jsroot = require("path/to/JSRootCore.js");
   One could parse ROOT JSON, read binary ROOT files (local and remote) and produce SVG.
2. Implement dropping of TTree object on the geometry drawing.
   This automatically invokes extract_geo_tracks() function, which
   should extract TGeoTracks from provided TTree.
   Example can be found in demo/alice_esd.js and in api.htm.
3. Implement projection of geometry on given plane.
   One could reuse drawing of geometry in other div (should be drawn with main option).
   In control GUI one could change position of the projection plane
4. One of the TGeo drawing can be assigned as main. When same object drawn next time,
   its drawing will be derived from the main. Useful for geometry projections.
   Also all tracks and hits will be imported from main drawing.
5. Let change background color of geo drawing.
6. One can change web browser title, providing &title="any string" in URL.
7. Introduce event status line, which is similar to ROOT TCanvas.
   Shown information similar to output in tooltip.
   One can enable both tooltips and status line at the same time.
8. Introduce JSROOT.GEO.build function to create three.js model for
   any supported TGeo class. Such model can be inserted in any three.js scene
   independent from normal JSROOT drawings.
9. Improve rendering of geometries with transparency. Use EVE approach, when transparent
   objects rendered after opaque and without writing depth buffer. Provide different
   methods to produce render order for transparent objects.
10. Let specify initial zoom factor for geometry like opt=zoom50.
11. Support also TPolyMarker3D class in geo painter.
12. Implement TGeoScaledShape.
13. Limit complexity of composite shape. If it has too many components, only most left is used.
14. When produce canvas or pad screenshot, render 3D objects with SVGRenderer.
    Allows to combine 2D and 3D objects in same PNG image
15. Improve MathJax.js output. It scales correctly in Firefox, makes correct alignment
    and works significantly faster.
16. When creating image in SVG format, correctly convert url("#id") references
17. Use latest three.js r85
18. Fix 'transpXY' URL parameter handling - it was used as opacity, but opacity=1-transparency

5.1.2

1. Fix - support newest TFormula in TF1 (#127)
2. Fix - ignore NaN value in saved TF1 buffer
3. Fix - correctly treat transparency in geo painter
4. Fix - disable useFontCache for SVG mathjax output
5. Fix - produce PNG image for objects with special symbols in names

5.1.1

1. Fix - invoke callback in JSROOT.draw() at proper time
2. Fix - support TGeoHMatrix, produced after GDML conversion
3. Fix - support also TGeoScale and TGeoGenTrans matrices
4. Fix - update histograms with all provided functions (#125)

5.1.0

1. New 'float' browser kind overlays with objects drawing
2. Browser can be enabled after drawing with 'nobrowser' mode
3. One can hide browser or switch browser kind at any time
4. New 'horizontal' and 'vertical' layouts for object display.
   One could configure several frames, each divided on sub-frames.
   Like display=horiz231 will create three horizontal frames,
   divided on 2,3 and 1 sub-frames.
5. Optional status line where current tooltip info will be shown
6. Improve enlarge functionality - now works with all layouts
7. Do not display all canvas tool buttons by default - provide toggle button instead
8. Let move TAxis title, its position now similar to ROOT graphics
9. Support 'col0' option for TH2Poly class to suppress empty bins
10. Implement for TH3 'box2', 'box3', 'glbox2', 'glcol' draw options
11. Support more superscript/subscript letters in normal text output
12. Correctly handle unzoom with logx/logy scales
13. Let disable stamp parameter in file url with "-" sign at the end of file name
14. Let use quotes in the URL parameters to protect complex arguments with special symbols
15. Introduce direct streamers - like TBasket or TRef
    Benefit - one can add custom streamers of such kind or reuse existing
16. Handle TMatrixTSym classes in I/O
17. Correctly count TH3 statistic in TTree::Draw
18. Recognize bower installation when "bower_components/jsroot/scripts" string
    appears in the script path (#120)
