Normandy's Preference Rollout code sets default values on prefs, not user
values (see uses of PrefUtils.setPref() in PreferenceRolloutAction.jsm).
Default prefs are not persistent; unlike user prefs, changes to default pref
values are not stored on disk. Changes to default values are only made on the
in-memory copy of the pref's value, and thus don't survive a browser restart.
Normandy changes the rolled out prefs early on in the startup of the browser,
but not before gfxPlatform::Init() runs. So that means gfx can't use Normandy
pref rollout to gradually rollout WebRender to release, as
gfxPlatform::InitWebRenderConfig() won't see the rolled out version of the
pref in time to turn on WebRender.
So to work around this, add a profile-before-change shutdown observer that
saves the default value of the gfx.webrender.all.qualified pref to a new user
pref, gfx.webrender.all.qualified.default. We check that on startup and
emulate the behavior that the pref system would have if that pref default
value had already been set by Normandy.

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.

This commit adds a scroll origin, nsGkAtoms::relative, which can be used to
mark main thread scrolling that can be combined with a concurrent APZ scroll.
The behavior of this is controlled by a pref, apz.relative-update. This pref
is initially activated and is intended as an aid to narrowing down causes
of regressions for users in bug reports.
Relative scroll updates work by tracking the last sent or accepted APZ
scroll offset. This is sent along with every FrameMetrics. Additionally,
a flag is added to FrameMetrics, mIsRelative, indicating whether the
scroll offset can be combined with a potential APZ scroll. When this
flag is set, AsyncPanZoomController will apply the delta between the sent
base scroll offset, and sent new scroll offset.
This flag is controlled by the last scroll origin on nsGfxScrollFrame. The
new origin, `relative`, is marked as being able to clobber APZ updates,
but can only be set if all scrolls since the last repaint request or
layers transaction have been relative.

This is not really the best fix (a better one would be to ensure that the
displayport is set on the root element of the gfx sanity window), but should
do as a stopgap solution.

This is what we have been working towards in all of the previous parts
in the series. This subclasses AnimationFrameDiscardingQueue to save the
discarded frames for recycling by the decoder, if the frame is marked as
supporting recycling.

Add a pref called gfx.font_ahem_antialias_none which disables
antialiasing for any font with the family name "Ahem". This is useful
for wpt reftests where antialaising of Ahem causes spurious failures.

This was an experiment before we had e10s. It's no longer needed.

This changes the containerful scrolling pref to be an override pref
such that it is:
- always false on desktop (i.e. always use containerless there)
- always true in Fennec (i.e. never use containerless there)
- true in GeckoView if WebRender is disabled (i.e. only use
containerless with WebRender).
The first two cases are the same as before; the last case is new.
Because we don't create layers with WR, the containerless vs
containerful distinction doesn't make much sense there, and we need to
implement a bunch of zooming glue in either case. So it makes sense to
go with the "way of the future" and keep it containerless.
