Dominik StrebelandClaude Opus 5.5 08b7b5eb15 Charts: bars draw their series' pattern fill and no fill ...

A bar series' own fill was read only when solid or a gradient: a pattern
(a:pattFill) was dropped, and an a:noFill series was read but drawn in the
palette's colour anyway, because the chart renderer turned every fill into
one colour and fell back to the palette for anything but solid. PowerPoint
for Mac draws the pattern, leaves an a:noFill bar empty and draws its
outline (c:spPr/a:ln) where it has one: a synthetic column chart with a
red-on-yellow dkDnDiag series, an empty series with a 3 pt blue outline
and an empty one without, exported as PDF, shows exactly that, legend
keys included.

- The chart reader reads a:pattFill (dml::pattern, shared with shapes);
  the chart writer writes it back for an edited chart.
- Bars and their legend keys paint with the series' or point's own fill:
  a colour, a preset pattern (pattern::fill) or nothing, then the series'
  solid outline at its width.
- Lines, areas and markers, which take one colour, use a pattern's
  foreground colour instead of the palette's.
