Built-in linebreaking logic.

Object allowing glyph drawing, containing cache state. Manages glyph positioning cacheing, glyph draw caching & efficient GPU texture cache updating and re-sizing on demand.

Describes horizontal alignment preference for positioning & bounds.

Built-in GlyphPositioner implementations.

Indicator that a character is a line break, soft or hard. Includes the offset (byte-index) position.

Describes vertical alignment preference for positioning & bounds. Currently a placeholder for future functionality.


Common glyph layout logic.

Logic to calculate glyph positioning using Font, SectionGeometry and SectionText.

Producer of a LineBreak iterator. Used to allow to the Layout to be line break aware in a generic way.


Helper function to generate a generate a transform matrix.
