SlintPlot 0.4.2

Fixed

• SegmentedRingChart, TileGridChart, and the slices and rings of pie,
  doughnut, polar area, radial bar, gauge and sunburst charts: on Linux,
  Windows and in browsers, where Slint draws with femtovg, some cells merged
  into solid bands and gaps closed, on one half of a segmented ring chart and
  in every tile grid. Slint's femtovg renderer works out from a shape's
  points whether it is solid or a hole, leaving out the closing edge, so the
  answer depended on where the shape was; it draws a hole's smoothed edge a
  pixel outside it. Every shape is now drawn counterclockwise and back to its
  start, which Slint takes as solid wherever it is.
