Detailed Description

Glyph arrangement — the result of text layout, containing positioned glyphs for each line.

This is the Pulp equivalent of shaped, laid-out text.

Uses Skia's HarfBuzz-based text shaper internally for:

• Complex script shaping (Arabic, Devanagari, Thai, etc.)
• Bidirectional text (via ICU)
• Font fallback for missing glyphs
• Kerning and ligatures
