[FEAT] Added protovis pv.DomNode.childIndex() method
[FEAT] Added 'strokeLineJoin', 'strokeLineCap', 'strokeMiterLimit' and 'strokeDasharray' to protovis and protovis MSIE; these are now usable in rules, in bar, panel and circle borders, and in any *not-segmented* lines and areas.
[FEAT] Protovis now prevents text selection with mouse
[FEAT] Moved localProperty from pvc.js namespace into protovis
[FEAT] Added interception support to protovis properties; it is now possible to call 'this.delegate()', from within an extension point, to call the inherited or default implementation.
[FEAT] When debugLevel>=15 (query string parameter), the padding-box and the border-box are shown with a colored stroke, helping in debugging layout issues.
[FEAT] Legend bullets are now sensitive to selected data points, and are hoverable and selectable (just like a dot in a line chart).
[FEAT] New def.OrderedMap class.
[FIX] Fixed tipsy bug that did not hide the tooltip when the text is empty and previously was not.
[FIX] In protovis, fixed number format rounding error due to IE9 incorrect behavior
[FIX] In protovis, fixed another (hopefully the last one) stack corruption bug
[FIX] In protovis, when animating, events are no longer triggered; this prevents user interaction messing with an ongoing amination.
[FIX] In protovis-msie, added a font substitution feature, to prevent standard font names, like sans-serif or serif, not being correctly shown.
[FIX] In protovis-msie, for 64 bit IEs, only certain white-listed font family names are allowed. These IE versions don't play well with unknown font families.
[FIX] In protovis-msie, a weird IE bug prevented that the last VML element added in a render would not be shown.
[BREAK] The extension point id argument of pvc.BaseChart#extend should no longer contain the suffix "_".
[WIP][FIX] Fixed an issue in the continuous ticks overflow padding calculation that resulted in unnecessary margins when the rounding mode was not 'tick' (time series data has no 'tick' rouding mode and always suffered from this bug).
[WIP][FIX] Fixed hovering in the Line panel; making an intermediate scene active would not highlight the corresponding "real" dot; now, when an intermediate scene is activated, it activates its owner scene instead; the same kind of issue still exists with interpolated scenes.
[WIP][FIX] In metric dot chart, the bubble border now uses the new strokeDasharray syntax for negative sizeBy values, and regained its darker-than-the-fill-color stroke color for positive sizeBy values.
[WIP][FIX] Several layout issues in the abstract title panel.
[WIP] clickAction and doubleClickAction are now local to each panel.
[WIP] pvc.BasePanel now has a signs collection.
[WIP] Re-added the document level mouse events of the Select behavior.
[WIP] Changed the way extensions are interpreted by panels. Panels now have an extension prefix that is prepended to the relative extension ids of the signs of that panel. The chart extend method retains its absolute interpretation.
[WIP] The extension points object is processed upon chart preRender to make it faster to lookup specific extensions.
[WIP] Added a JS "parent" get property to pvc.visual.Scene so that the now unsupported idiom "this.parent.index" is easily spotted.
[WIP] Added scenes, signs and V1 compatibility wrapping to the Axis panel, Title panels, and Base panel; remaining common elements work is: the FullGrid lines, the Frame box (older End lines), the Zero lines, the "scale" and the tooltip extension points.
[WIP] All signs now wrap extension point functions so that they're called with the "standard" extension point function signature.
[WIP][REFAC] The axis panel no longer has custom selection methods and is now using all the pvc.BasePanel implementations.
[WIP][REFAC] Several changes in the sign classes.
