Enum CacheResult 

enum CacheResult {
    CachedAndRendered,
    UnsupportedTransform,
    AtlasFull,
}

Outcome of a cache-first render attempt.

Callers use the variant to decide whether to fall back to direct rendering.

Variants

CachedAndRendered

Glyph was rasterised, stored in the atlas, and drawn. No fallback needed.

UnsupportedTransform

Transform contains rotation or skew — cannot be cached at a single raster resolution, so the caller must render directly.

AtlasFull

Atlas allocator could not fit the glyph (page full, eviction didn’t free enough space, or the glyph exceeds the page dimensions).
