Added support for the right-to-left content direction.
Fixed: word-wrapping algorithm does not work correctly with right-to-left languages.
Fixed: Page.Size() API incorrectly uses Unit.Inch as default unit. Replaced with Unit.Point for consistency.
2022.9.0
- Implemented font-fallback algorithm,
- Introduced new Settings API,
- Significantly reduced memory allocation cost for TextStyle objects,
- Implemented optional checking if all font glyphs are available,
- Minor text-rendering optimizations.
2022.9.1
- Fixed: text hyperlinks do not work when the CheckIfAllTextGlyphsAreAvailable option or text fallback are used,
- Fixed: cells with RowSpan (greater than 1) are not always displayed properly,
- Improved predictability of the Inlined element when measuring its children.
