LoadFromCache implements imagor.Cacher. w and h are the requested output dimensions used to determine cache eligibility, not to select a blob of that size. Returns (nil, false) when w or h is zero (unknown size) or exceeds CacheMaxWidth×CacheMaxHeight — the cache holds a downscaled copy and cannot s

// loadOrCache returns a cached blob for the given image path, using the image cache.
// Cache key is image path only, so the same source serves all requested sizes.
