// A Chromium-specific version of the skresources::ResourceProvider API, which
// allows the code driving the animation to specify which image should be used
// for each asset in each frame of the animation. Callers rendering Skottie
// animations that may have images embedded in them must implement this API. In
// the most basic case where an image asset does not change throughout the
// course of the animation, the same image can be provided for every frame. But
// more complex logic such as providing a different image at the start of each
// animation cycle can be implemented if desired.
//
// Implementations are not required to be thread-safe (the provider and its
// ImageAssets shall always be invoked from the same sequence).
