We were getting the proper app units value for transform matrix offset before
Bug 1384656. But after that bug we started using GetCalcValue() method and
it wasn't converting length to app units and this was cousing to miscalculate
translate functions in transform property.

This method can be extremely hot, so we need to remove all sources of XPCOM
overhead from it. This includes the usages of weak pointers (thanks to the
previous parts), refcounting, and QueryInterface.
I kept the callers hold the selection controller alive by assigning the
return value to an nsCOMPtr in places where the methods called on it could
have a remote chance of messing with the lifetime of objects.
We need to create a WebRenderAnimationData item in order to preserve the

This patch move common canvas interfaces out of layer. So I create a
base class CanvasRenderer which move interfaces from CanvasLayer.
CopyableCanvasRenderer from CopyableCanvasLayer, ClientCanvasRenderer
from ClientCanvasLayer and WebRenderCanvasRenderer from
WebRenderCanvasLayer. And finally, WebRenderCanvasRendererSync for the
non layers free mode and WebRenderCanvasRendererAsync for the layers
free mode.
Summary all changes in this patch.
* Move class CanvasLayer::Data to CanvasRenderer.h and rename it to
CanvasInitializeData. Because this class not only use by layer but also
* Move BasicCanvasLayer::UpdateSurface to
CopyableCanvasRenderer::ReadbackSurface.
* CanvasClient::Update now accepts ShareableCanvasRenderer as parameter.
not CanvasLayer.
use by layers-free mode. Move it out of layer's class makes more sense.
* Add InitializeCanvasRenderer in the canvas related classes to
initialize CanvasRenderer without involved layer.
* All canvas layer has function "CreateCanvasRendererInternal" that
initialize corresponding CanvasRenderer.
* Description of all CanvasRenderer classes:
** CanvasRenderer: Based classes.
** CopyableCanvasRenderer: Can readback canvas content to a
SourceSurface. Use by BasicCanvasLayer.
** ShareableCanvasRenderer: Provide IPC capabilities that allow sending
canvas content over IPC. This is pure virtual class because the IPC handling is
different in different LayerManager.
** ClientCanvasRenderer: Implement IPC handling for ClientLayerManager.
Use by ClientCanvasLayer.
** WebRenderCanvasRenderer: Implement IPC handling for
WebRenderLayerManager.
** WebRenderCanvasRendererSync: Use by WebRenderCanvasLayer.
** WebRenderCanvasRendererAsync: Use by layers-free mode in WebRender.

In while-loop [1],
1. The first SetMatrix call that I remvoed in this patch is totally useless,
we can just pass initialMatrix to contextPaint, instead of set initialMatrix
to aContenxt and read back from aContext and then pass it to contextPaint.
2. This function, SVGTextFrame::PaintSVG, is the only caller of
SetupStrokeGeometry, and it does not need SetupStrokeGeometry to setup matrix at
all, since it will be overwritten the transform matrix of aContext at several

We have to set mHaveNonAnimationRestyles if we have attributes changed
(note: we increase the animation generation only if mHaveNonAnimationRestyles
is set). Attributes changed may create a new transition, and we use the
animation generation as the order of the transition, so
Element::GetAnimations() can return transitions with correct order.
Besides, I think ContentStateChanged() will not trigger a new
transition, so we don't need to make mHaveNonAnimationRestyles there.

The patch provides FFI access to Gecko's SeenPtrs type from Rust, in order to
record what has already been measured when measuring Arcs. (The SeenPtrs must
be initialized on the Gecko side because the same table is reused for measuring
all Elements within a window, because Elements can share ComputedValues.) I
have confirmed with DMD that this is working correctly.
The patch also introduces MallocSizeOfRepeats, which is like MallocSizeOf but
takes a SizeOfState, which holds a SeenPtrs table.

When display style is changed from 'none' to other in animation-only restyle
we need to resolve descendant elements' style that were in the display:none
subtree.
Three possible ways to resolve the descendant elements' style;
1) Traversing unstyled elements in animation-only restyle
We can't simply traverse unstyled elements in the animation-only restyle
since when we decided to traverse the unstyled elements we don't know yet
the elements will be initially styled or are in display:none subtree. It
will result that the new elements are styled in animation-only restyle,
it's undesirable.
2) Creating a SequentialTask and resolve the descendants' style with
ServoStyleSet::StyleNewSubtree()
We can't resolve the descendants' styles with ServoStyleSet::StyleNewSubtree()
in SequentialTask since at the moment we are still in servo traversal (i.e.
sInServoTraversal is true). That means AutoSetInServoTraversal fails
in PrepareAndTraverseSubtree().
3) Creating a SequentialTask and set restyle subtree hint and defer descendants'
restyle in a subsequent normal traversal
Note that, when we process throttled animations flush, we don't process
normal traversal so the descendants will not be traversed until normal
restyle happens but it will not be a big problem since it's really rare
that user clicks display animation element just at the right moment when
display property changes from none to other. Also, if it will be really
a problem, we should process *only* transform animations on the compositor,
it's ideally right thing to do. Display property never runs on the
compositor.
This patch takes the third approach.

When a container layer's transform has an animated scale, we clamp it
to a near power of two so that descendent layers' resolutions do not
keep changing and we minimize repainting. The current behaviour only
clamps the scale when it has not changed with respect to the previous
transaction. In animations where the scale usually changes, but
happens to remain constant between two consecutive transactions, this
is bad.
Rather than only checking against the previous scale value, use
ActiveLayerTracker::IsScaleSubjectToAnimation() to determine whether
to clamp, as it takes into account a longer period.

Instead of the WebRenderLayerScrollData code knowing about all the
different display item types, it makes more sense to move this logic
into the display items.
In addition to avoiding dis-encapsulating the data from nsDisplayItem subclasses,
this makes it easier to handle two specific scenarios:
(1) the case where an nsDisplayItem A subclasses another nsDisplayItem B, but A
and B have different types returned by GetType(). Previously A and B would have
to be handled explicitly in the WebRenderLayerScrollData switch statements,
which doesn't scale well if new types are added. With the new approach the
virtual function is shared down from A to B and so takes care of it. This is
particularly relevant for types like nsDisplayOwnLayer which have a number of
subclasses.
(2) the case where a display item *might* have APZ-relevant information.
In this case the type of the item alone is not sufficient to determine
if we need to create a new WebRenderLayerScrollData for it. Instead, we
need to access specific state inside the display item. This is now
handled by the UpdateScrollData function returning true when passed
nullptr arguments, and replaces the switch statement in
WebRenderLayerManager that updated forceNewLayerData.

Because we want to remove nsAdoptingString. We have other variants that don't
use nsAdoptingString, which can be used instead. There are three basic
patterns.
1. The easiest case is when we don't check for success.
> nsAdoptingString s = Preferences::GetString("foo");
> foo(s);
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> foo(s);
2. The next case is when we check if the result is empty.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s.IsEmpty()) { ... }
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> if (s.IsEmpty()) { ... }
3. The final case is when we null check the result.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s) { ... }
becomes:
> nsAutoString s;
> nsresult rv = Preferences::GetString("foo", s);
> if (NS_SUCCEEDED(rv)) { ... }

nsMenuPopupFrame will constrain the size of its widget to its min and max size.
It will also request its nsView to resize to its frame rect. If its frame rect
is larger or smaller than the min or max size, nsView will be unable to change
the size of the widget, and each ViewManagerFlush will attempt a resize and
force a composite. When there are a lot of ViewManagerFlushes, this can
overload the compositor.

This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.
The patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.

This doesn't actually implement style context reparenting in the style set yet; that part is next.
There is one behavior difference being introduced here compared to Gecko: we
don't reparent the first block piece of an {ib} (block-inside-inline) split
whose first inline piece is being reparented. This is actually a correctness
fix. In this testcase:
<style>
#target { color: green; }
#target::first-line { color: red; }
</style>
<div id="target">
<span>
<div>This should be green</div>
</span>
</div>
Gecko makes the text red, while every other browser makes it green.
We're preserving Gecko's behavior for out-of-flows in first-line so far, but
arguably it's wrong per spec and doesn't match other browsers either. We can
look into changing it later.

The details element, which is a sibling of an animating element, is checked
whether the element needs to be processed in a post traversal for throttled
animation flush because the parent element has animation-only dirty bit (i.e.
the parent element is a common ancestor of the animating element and the
details element). Also at the moment of the check the details element has
reconstruct frame damage because 'open' attribute is changed. Thus in the check
