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.

nsLayoutModule must be initialized in order to call into JS, but I
don't want to have to rely on calling a service in that
module. Instead, always initialize the module very early in component
manager initialization. This also makes initialization more
consistent, so things like errors in manifests won't affect when it
happens, which can result in different behavior in different builds.
I also made nsLayoutModule initialization infallible, because I can't
imagine that we can do much that is useful without it.
Another change I made is that gInitialized is set to true even in a
GPU process. This simplifies checking whether initialization has
happened already when we start up the layout module.

This patch basically reverts the functional part of changeset 52bd865d757c.
I'd optimistically hoped we could skip this early-freeze in order to compute &
report a bit more "potential flexing" information via devtools. Bbut it turns
out that breaks assertions & produces bogus information for flex items whose
base size vs. min/max-clamped "hypothetical" sizes are very
different. (Specifically: it produces nonsense for flex items whose base sizes,
if unclamped, would reverse the directionality of flexing.)

We need to correctly populate the cumulative resolution field in the
ScrollMetadata in order to support zooming. Without this, the cumulative
resolution doesn't include the presShell resolution, and that results in
APZ getting into an inconsistent state.
Currently, the cumulative resolution is populated from the
ContainerLayerParameters object's scale, but in the case of WebRender,
we call ComputeScrollMetadata with an empty ContainerLayerParameters
since don't actually do layer building or rasterization in Gecko.
This patch makes this more explicit by changing the argument to a
Maybe<ContainerLayerParameters> and passing Nothing() from the WebRender
call sites.
In this scenario, we just use the cumulative presShell resolution as
the cumulative resolution, which should be correct for WebRender as
we won't have an "extra" CSS-derived resolution applied on the Gecko
side.

This patch also updates the expectations in the mochitest test_flex_items.html.
Before this commit, the test (incorrectly) expected the mainBaseSize API to
return some items' *final sizes*, because that's what our implementation did
return, up until now. As of this patch, that API will now return the item's
actual flex base size, which means the text expectations need to change.
I'm also adding a new flex item to the test, to exercise a formerly-untested
scenario. And to accommodate this new item, I'm also doubling the width of

Frozen flex items have already been clamped to their min/max sizes, so their
size-change isn't a "how much we want to flex" measurement, and it's not useful
for determining whether the rest of the line is shrinking.
This patch is just adding a `if (!item->IsFrozen())` check around some code,
and reindenting that code, and adjusting a few comments.
This change is necessary to avoid failing the "GrowthState" assertions,
because (for example) a flex item that's clamped to a small max-width
could fool us into thinking we're in a "shrinking" state (since its final
size is smaller than its base size), even though really we're
in a "growth" state and the item was simply clamped. We avoid this
problem by skipping (potentially-clamped) frozen items when determining
the line's GrowthState.

compute this tentative size, even though they can never have it.

PresShell::PageMove() climbs up to parent document when there is no scrollable
parent in current document. However, if aExtend is true, it should expand
Selection in the document itself. Therefore, it needs different rules to
look for container of expanding Selection from scrollable element to scroll.
Additionally, old rules (i.e., before the fix of bug 1369072 which caused
this regression) were also buggy. It used parent scrollable element or
root scrollable element simply. Therefore, if found scrollable element is
ancestor of selection limiter, it didn't work as expected.
This patch creates nsFrameSelection::GetFrameToPageSelect() to retrieve
per-page selection container element with the following rules:
- look for a scrollable element in selection limiter.
- if there is no scrollable element, use selection limiter.
- if there is no selection limiter, use the root frame.
So, nsFrameSelection::CommonPageMove() should take nsIFrame rather than
nsIScrollableFrame since container of per-page selection may be used in
non-scrollable contenteditable element. If it's called with non-scrollable
frame, it needs to compute the expanding range with the frame size.

When we're creating a scrollframe with let's say, display: flex or grid, the

This is the only caller that (incorrectly) passes the same frame to

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.
