classGlyphAtlas

@codexo/exojs / rendering / stable

A per-font-variant glyph atlas with automatic multi-page growth. In `'sdf'` mode (default) each atlas page is a single-channel R8 `DataTexture` populated by GlyphSdf. One `GlyphSdf` instance is kept per font size so the atlas can mix sizes efficiently. In `'color'` mode pages are RGBA canvas textures that preserve full glyph colour data for emoji and colour fonts.
