1.13.0

• Series colors follow Mermaid's palette theme variables: pie1–pie8 in pie charts, git0–git7 in git graphs, cScale0–cScale7 in timelines, radar charts and treemaps, cScale1–cScale8 in mindmaps, venn1–venn8 in Venn diagrams, and the first eight colors of xyChart.plotColorPalette in XY charts. Shorter Venn and XY palettes repeat. Values that aren't colors keep the theme's color. #55 #98
• Labels on palette colors in pie charts, git graphs, timelines and treemaps use whichever of --pele-fg-on-light and --pele-fg-on-dark contrasts more.
• Edges that cross a subgraph's border bend less near the nodes they meet, and more edges come out straight. #97
• Unlinked nodes in a subgraph stay lined up when an edge from outside enters one of them, instead of that node dropping a rank.
• Block: labels in blocks that span several columns use the extra width to fit on fewer lines. #106 #107
• Quadrant: the quadrantChart settings titleFontSize, quadrantLabelFontSize, xAxisLabelFontSize, yAxisLabelFontSize and pointLabelFontSize set text sizes, as in Mermaid. Point labels wrap at the plot width instead of 200 pixels. #108 #109
