This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

I'm drive-by removing the comment about the frame tree state because I looked
into it, and the answer is: we properly restore it.
The gotcha is that we retain it too much, indeed, we retain it enough that it
can leak. See bug 1397239.

After the fix to bug 1294442 and bug 1324499, ResizeReflow began to be called
twice for each DOM update in webext popups, and we also artificially re-set the
scroll outside of ResizeReflow to counter the DidDoReflow callback in
nsHTMLScrollFrame setting scrolltop to zero due to the first reflow, which is
done with unconstrained height.
Because of the scrollport being reset we get spurious DOM scroll events.
Replacing the scrollport also interrupts smooth scrolling.
Move the double-reflow down one level into PresShell, doing it before
DidDoReflow is called. The scrollport is no longer reset (causing a spurious
scroll event), and we don't need to replace it (interrupting smooth scrolling).
Also partially fixes bug 1396034.

These functions are now dead code. And really, they were already dead code
even before this patch-stack -- they were only called in never-evaluated
(and now-deleted) #else clauses.

This patch drops all MOZILLA_INTERNAL_API checks (and the bodies of any
associated "#else" clauses) from these files. The basic assumption here is
that MOZILLA_INTERNAL_API is #defined in all (supported) compilation units that
#include these files, so the checks are superfluous and the #else clauses are
dead code.
(If this assumption is mistaken and there is some .cpp file in our codebase
that #includes this header and yet does not have MOZILLA_INTERNAL_API, we will
find out via bustage on treeherder.)

When there is no selection and no focused content, aContent of
nsIPresShell::GetScrollableFrameToScrollForContent() is nullptr. Then, it'll
use root scrollable frame to scroll. However, the root scrollable frame may
be not scrollable. In such case, ancestor document's scrollable frame should
be scrolled instead.

We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

There's only one case of sync frame construction from ContentRemoved now, and
it's not on the element being removed, but on the whitespace siblings if needed,
and _only_ when they don't support lazy frame construction.
Basically, this switches all the RecreateFramesForContent calls to use
`aAsyncInsert` (which I changed to an enum class for readability), except when
we're already reframing.
Also, it switches ReframeTextIfNeeded to opt-in into lazy frame construction,
since it's used only when aFlags == CONTENT_REMOVED.
This allows to simplify the DestroyFramesFor API (which I'm happy to rename to
something more meaningful, since now it's something like
DestroyFramesForAndRecreateThemAsync), and do some other consistency cleanups.
A bunch of the ContentRemoved callsites were pretty random at passing
aAsyncInsert, and that was some kind of a mess. This patch ensures consistency,
and makes it impossible to do O(n^2) work when removing DOM nodes, which is
nice.
The underlying reason for this is explained in the description of bug 1377848,
and basically allows us to remove a bunch of Servo hacks on the longer term (a
few of them are going away already, yay!).

This patch does the following.
- Moves nsWindowSizes from nsWindowMemoryReporter.h to its own file,
nsWindowSizes.h, so it can be included more widely without exposing
nsWindowMemoryReporter.
- Merges nsArenaMemoryStats.h (which defines nsTabSizes and nsArenaMemoryStats)
into nsWindowSizes.h.
- Renames nsArenaMemoryStats as nsArenaSizes, and nsWindowSizes::mArenaStats as
nsWindowSizes::mArenaSizes. This is the more usual naming scheme for such
types.
- Renames FRAME_ID_STAT_FIELD as NS_ARENA_SIZES_FIELD.
- Passes nsWindowSizes to PresShell::AddSizeOfIncludingThis() and
nsPresArena::AddSizeOfExcludingThis(), instead of a bunch of smaller things.
One nice consequence is that the odd nsArenaMemoryStats::mOther field is no
longer necessary, because we can update nsWindowSizes::mLayoutPresShellSize
directly in nsPresArena::AddSizeOfExcludingThis().
- Adds |const| to a few methods.

This commit changes async keyboard scrolling to be enabled only if the content to
scroll is from a selection. This works around the problem of detecting whether
an arbitrary element has key listeners that should prevent async key scrolling,
because when they have the focus we will have disabled async key scrolling.

Focus can change at any moment in a document. This causes non-determinism and
correctness problems for doing keyboard apz scrolling. To get around this, we
will maintain deterministic behavior for focus changes initiated by input events
and see if we can get away with more non-determinism for things like `setTimeout`
In order to do this, we disable async keyboard scrolling when an input event is
processed that could have a event listener. We then attach a sequence number to
that input event and dispatch it to content. In content, we record the highest
sequence number that we have processed from an event, and send that on each focus
update. Using this, we can determine in APZ if we have a current focus target or
if we are still waiting for an input event to be processed and focus to be
reconfirmed.

This commit modifies PresShell and nsDisplayList to send a FocusTarget update on
every layer transaction. Ideally we would like to send updates as often as possible,
but this seems like it works well. This can be iterated on later, if necessary.

This commit begins the work needed for tracking focus by creating two new classes,
FocusTarget and FocusState. FocusState is created and used by APZCTreeManager to
track the global focus information, while FocusTarget is created per layer tree and
sent to APZ with local focus information. Between the two we are able to figure out
what the correct scrollable layer is to use in response to a keyboard scroll.
See the comment in `FocusState.h` for more details on the architecture and things
needed in future patches to complete this.

I've chosen this approach mainly because there's no other good way to guarantee
the model is correct than holding the snapshots alive until a style refresh.
What I tried before this (storing them in a sort of "immutable element data") is
a pain, since we call into style from the frame constructor and other content
notifications, which makes keeping track of which snapshots should be cleared an
which shouldn't an insane task.
Ideally we'd have a single entry-point for style, but that's not the case right
now, and changing that requires pretty non-trivial changes to the frame
constructor.

It's not only inefficient, but also prone to buggyness. Since styles may not be
up-to-date when it happens.
Post a reconstruct instead, which ensures a style flush happens before running
frame construction.

We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

Prior to this patch, dumping of style contexts in the layout
debugger would only dump the subtree associated with the root
frame, which just covers the viewport, canvas, and associated
scrollbars.
I think this has been broken since bug 236921 (2004) and
bug 378693 (2007) properly disconnected the root element from the
styles for the viewport and canvas.
This patch just manually dumps the root frame and the root
element's frame, since the style set no longer maintains a list
of all of the style context roots.
