font_cache

Caller-owned cache for font resolution, parsed faces, and glyph masks.

Pass one FontCache through the cache= overloads of text measurement and drawing functions. Font discovery is initialized lazily. Parsed faces are keyed by path and pixel size; glyph masks are held in a bounded two-generation store.

Structs

• FontCache: Construct one, then pass it by cache= into draw_text/measure_text/measure_text_block for every call reusing the same fonts. No cleanup, and no setup: the one font scan happens on the first lookup, and every later lookup skips it.
