This was added in bug 780692 to work around assertions that arose due to the
inconsistent state introduced by mini-flushes. However, that workaround
no longer seems necessary. In particular, the crashtest for bug 813372 no
longer reports failed assertions when we remove this method and nor do any
other tests.
I'm not sure exactly what changed about how we do mini-flushes but I suspect
it was bug 960465 or one of the related follow-ups.
In nsDisplayListBuilder keep track of the total area of frames which
have been made animated geometry roots due to having animated offset or
margin properties. This is in order to reduce the total area of created
layers. Once the area has reached a certain limit do not allow any more
frames to be AGRs for this reason.
Currently this only applies to AGRs created due to frames having
animated offset or margin properties. This is because we believe this is
a major source of over-layerisation and too high memory usage. This
could easily be extended to include the creation of AGRs due to other
reasons too.
Note that this technically limits the area of AGR frames, not the area
of layers, though it will have a fairly direct impact.

Add helper function nsIFrame::In3DContextAndBackfaceIsHidden() which
checks both if a frame is backface-hidden and whether it is within a
3D-transform context.
In FrameLayerBuilder, check this function rather than BackfaceIsHidden()
to determine whether a frame needs a backface-hidden layer. This will
avoid creating unnecessary extra layers for non-3d-transformed items
which for some reason have backface-hidden set.
On Fennec, it's possible that after automatically zooming an editable
input, the mImaginaryCaretRect for the caret remains the same. Only the
zoom level is changed. Therefore, the zoom level should also be
considered to determine whether the position is changed or not so that
the caret can get updated.

Nothing() represents linear function, i.e. skip calculation.
ParseEasing is changed to return a Maybe<ComputedTimingFunction>,
if timing function is linear function, ParseEasing returns Nothing().
This is a patch for compositor side to represent linear function as null_t/Nothing().
Also the first argument of ToTimingFunction changes to a Maybe<ComputedTimingFunction>.
As a result of this change we can also use ToTimingFunction for animation
effect's timing function.
This adds the value -moz-window-dragging: default as the initial value of the property,
and makes it a [reset] property. This allows us to change the way the window dragging
region is calculated: Elements with -moz-window-dragging: no-drag will now always be
undraggable, even if they are overlapped by -moz-window-dragging: drag elements. That
way we can keep the region calculation simple and don't have to add code to respect
z-ordering.

By changing signature of those two functions, we make compiler complain about
all their existing uses, so we can find all of them and convert them.
Some of the callsites of Get() with those properties are also converted, but not

This patch (currently WIP) alters the way we determine whether jank is user-visible or not.
Instead of measuring the total time spent doing JS, we now use an
indicator provided by the vsync driver: how long it takes to deliver
the signal from the vsync timer to the main thread. This lets us find
out more accurately if there is user-visible jank. In the future, this
will also let us add an observer to find out whether the process
itself is janky, regardless of JS.

Displayport margins change by small amounts on almost every single scroll. We do not want to update image visibility nearly that often.
As the comment, and the original bug (bug 1169881) suggest this is only meant to catch rather large changes in display ports as we already have means to trigger an image visibility update via a scroll position change and via any style or layout flush.
This is a regression from bug 1002992 where we switch from the display list builder to the frame tree walker and didn't update mLastUpdateImagesPos in the frame walker.
Native events come with timestamps indicating when they were created or
generated by the user. Using those, we can get a full picture of how long it
takes between the user trying to do something and us responding to it.
This is currently only for ports that populate WidgetEvent's timeStamp
(presently gtk, Windows).
All the event interfaces changed except for nsIDOMUIEvent and its inheritors.

RestyleManager currently has a piece of state for tracking if throttled
animations are up-to-date or not. Actually, it's not so much about throttled
animations but really about outstanding changes to animation styles (which
is typically expected to be due to throttling animations but there are
other cases that invalidate the animation style rule that we should be
considering here).
We now have that same information stored in the EffectCompositor so we can
remove the redundant state from RestyleManager. Furthermore, the state stored
in EffectCompositor is more accurate since it captures the case when animation
style needs to be updated twice within a tick, or when nothing needs to be
updated within a tick.
This patch, therefore, introduces EffectCompositor::HasPendingStyleUpdates in
place of setting RestyleManager::mLastUpdateForThrottledAnimations.
nsTransitionManager also uses mLastUpdateForThrottledAnimations to warn if we
have not processed throttled animations. We can't use HasPendingStyleUpdates
here however, since it will return true in the case where we have triggered new
transitions in the process of restyling. However, any new transitions will
trigger "standard" (i.e. not throttled) restyles so we introduce another
method, HasThrottledStyleUpdates, that returns true only if we have outstanding
throttled updates and use this for the warning inside nsTransitionManager.
nsPresContext contains a mLastStyleUpdateForAllAnimations flag which is simply
used to prevent unnecessarily posting restyles when throttled animations are
already up to date. Since part 13 we now accurately record whether we have
posted a restyle for each throttled animation and only post a restyle if we
have not done so already. As a result, this flag is no longer needed since
calling PostRestyleForThrottledAnimations is effectively a noop when throttled
animations are up-to-date.
Since we want to track elements needing a restyle on EffectCompositor we need
to scope it to an nsPresContext rather than just making if a collection of
static methods.
Even though the content of the root scroll frame is the root element, the primary frame of the root element is never the root scroll frame. This is even true if the normal primary frame of the root element is not created (say because it is display: none). Leaving the primary frame of the root element to be null even though there are frames (the root scroll frame, and the canvas frame) that have the root element as their content.
This behaviour is more consistent by not ignoring a root scroll frame when it exists.
And to several functions above it in the callgraph, ones that no longer need an
nsRenderingContext.

Instead do it when we first encounter the root scroll frame.
Doing this goes back to bug 635053, where we did it because fixed position items weren't getting included. However in bug 974643 we learned that this was wrong. Displayports aren't relevant to fixed pos content, displayports are only relevant to scrolled content. And we set the dirty rects of fixed pos content specially. The only other thing that should be affected is scrollbars, and we already carefully set their dirty rects too.
