v0.9.1

Bug-fix patch: DropDown / TreeView / Expander / Menu drew their triangle chevrons inverted from what the code comments described.

  • DropDown drew ▲ instead of ▼.
  • TreeView expanded chevron drew ▲ instead of ▼.
  • TreeView collapsed chevron drew ◀ instead of ▶.
  • Expander expanded drew ▲ instead of ▼; collapsed drew ◀ instead of ▶.
  • Menu nested-item chevron drew ◀ instead of ▶.

The trace bug in each case was the same: the loop wrote the narrow (1-pixel) tip on the row/column expected to hold the wide (7- or 9-pixel) base and vice versa. Fix is one character per site — swap the sign of the loop index in the coordinate that varies along the chevron's axis.

Compatibility

No API change. Consumers pinning v0.9.0 keep working; visual output flips to the intended shape on rebuild.
