/**
|
|
* An Image wrapper that disables animation, freezing the image at its first
|
|
* frame. It does this using two strategies. If this is the only instance of the
|
|
* image, animation will never start, because IncrementAnimationConsumers is
|
|
* ignored. If there is another instance that is animated, that's still OK,
|
|
* because any imgIContainer method that is affected by animation gets its
|
|
* aWhichFrame argument set to FRAME_FIRST when it passes through FrozenImage.
|
|
*
|
|
* XXX(seth): There a known (performance, not correctness) issue with
|
|
* GetImageContainer. See the comments for that method for more information.
