We need the code above because ImageSource::frameHasAlphaAtIndex does not decode the given frame.

However, the code above is not yet needed because ImageSource::frameIsCompleteAtIndex decodes the given frame.
A follow-up patch will change frameIsCompleteAtIndex() not to decode anymore, so the code above will be needed. I'll file another bug.
