feat(Contour): Stroke unfilled contours in the bands' colors when no stroke is given (#934)
feat(Frame|Grid|Axis|Highlight): Draw an isometric chart's back walls, their gridlines (<Grid z>), a height axis (<Axis placement="back">), and highlights at a point's height (#934)
feat: Support z heights on an isometric chart — boxes (Rect, Cell, Calendar, Bars with valueAxis="z"), floating Circle, Text, Labels and ArcLabel, Line stems, and extruded Polygon, Path, GeoPath, Contour, Pie, Area and Spline (#934)
breaking(Chart|Spline|Area): Rename the z grouping channel to g (ex. <Spline g="id">), freeing z for a third position (#934)
feat(TransformContext): Switch mode without remounting the chart (#934)
feat(Chart): Support view={isometric} to draw the plot area as a floor seen at an angle, turned with isometric({ rotate, tilt }) or by dragging (transform={{ drag: 'rotate' }}), with viewport text facing the viewer (#934)
feat(Ellipse): Support rotate to turn the ellipse about its center (#934)

fix(TransformContext): Zoom in / out about the middle of the plot area, and center a canvas zoom without resetting its scale (#934)
fix(GeoPath): Start a tweened map shape as itself rather than rising from a baseline (#934)
fix(Axis): Size an angle axis' ticks by its circle rather than the chart's width, so a continuous angle scale's tick count no longer changes with width (square charts get more ticks) (#934)
fix(Link): Draw links whose ends share an x or y (#934)
fix(BrushContext): Draw and measure the brush through a canvas pan / zoom (#934)
fix(TooltipContext): Account for transform.mode: 'canvas' pan / zoom in bisect modes and 'data' tooltip placement (#934)
