* animated codecs (i.e. msec = 0). Calling this multiple times (without calling seek())
* will always return the same image object (or null if there was an error).
sk_sp<SkImage> getFrame();
* Return the size of the image(s) that will be returned by getFrame().
SkISize dimensions();
* Returns the total duration of the animation in milliseconds. Returns 0 for a single-frame
* image.
uint32_t duration() { return fTotalDuration; }
* Finds the closest frame associated with the time code (in milliseconds) and sets that
* to be the current frame (call getFrame() to retrieve that image).
* Returns true iff this call to seek() changed the "current frame" for the animation.
* Thus if seek() returns false, then getFrame() will return the same image as it did
* before this call to seek().
