The previous value of the axis velocity could be stale, e.g. in the opposite
direction.

This patch allows us to intercept invalidation requests for display
items, and avoid regenerating the display list for animated images which
are using SharedSurfacesAnimation.
Differential Revision: https://phabricator.services.mozilla.com/D7504
This patch embeds a SharedSurfacesAnimation object inside an
ImageContainer. This allows any consumers of the container to get the
single shared ImageKey for an animation, despite whatever surfaces may
be held inside the container at a given time.

This is a non-functional change. It allows objects that build on top of
these helper classes to be exposed outside of SharedSurfacesChild in
future patches in this series.

Animated images will work by changing the external image ID that an
ImageKey points to. We cannot allow the old external image to be
released and potentially unmapped until we have produced a new frame
with the new external image ID. We currently wait until the epoch has
advanced, but in the future when we don't rebuild the scene to animate
an image, the epoch will remain the same. This could cause us to hold
onto no longer used surfaces for much longer than expected. As such, in
this patch we switch to waiting for a FrameRendered notification from
WebRender, which works even if the scene rebuild was avoided.

Animated images will require scheduling a composite of the frame in
addition to updating the ImageKey/external image ID bindings. It would
be good if this could be done as part of the same IPDL message.
Additionally a page may have many animated images that we update the
frame for at the same time, so these updates should be batched together.
In the event that we needed to regenerate the display list, or produce
an empty transaction, ideally we would just throw these resource updates
in with the rest of the changes. This patch allows us to do all of that
without unnecessarily burdening the caller with tracking extra state.

Async animated images need a single ImageKey which can point to any
frame represented by its own external image ID. Additionally a frame
could be referenced again directly (e.g. something shows/uses the first
frame of the animated image).
Before this patch, the ownership between an ImageKey and an external
image ID for a shared surface was not clearly expressed. This resulted
in a special command to release the reference to the external image
separately from deleting the image key.
This patch makes the strong reference to an external image ID and an
ImageKey directly related. Not only does this facilitate multiple
ImageKeys owning the same surface, it also simplifies the ownership
semantics.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

I added this condition in the relative scroll update patches, but had
meant to clean it up to be idiomatic C++ and forgot to.

The implementation of deferred transforms did not handle the case where
we ended up deferring multiple transform items in a row with different
ASRs. In this case, when we encounter the nested transform item that we
want to defer, we need to flush the previously-deferred transform item
into a WebRenderLayerScrollData item. This patch accomplishes that, and
includes a mochitest that exercises the relevant behaviour.
