// Provides a minimal wrapping of the Blink image decoders. Used to perform
// a non-threaded, memory-to-memory image decode using micro second accuracy
// clocks to measure image decode time.

// TODO(noel): Consider integrating this tool in Chrome telemetry for realz,
// using the image corpora used to assess Blink image decode performance. See
