When focus is moving from a remote process to different process (including to the main process), destroying IMEContentObserver in the focused remote process occurs later. I.e., NOTIFY_IME_OF_BLUR will be notified later. However, it may be too late for new focused process especially when destroying the focused widget.
Therefore, this patch makes IMEStateManager notifies IME of blur in such case.

Requests to commit/cancel composition came from remote process with sync message. So, it may be too late. E.g.,
* If the process already sent new composition start but is not handled by the remote process yet.
* If the process already send commit message but it's not handled by the remote process yet.
* If focus was already moved to different process.
In the former 2 cases, the remote process should wait eCompositionCommit(AsIs) events for clearing TextComposition. Therefore, the requested should be treated as it's handled asynchronously.
In the last case, the remote process should commit composition with latest composition string in the main process because if the remote process commits composition with "current" composition string in it, user may lost some inputted text.

Then, input context for the widget is marked as for main process but the widget still have IME focus of a remote process.
For fixing this mismatch, IMEStateManager should set ORIGIN_CONTENT even when the tab parent is being destroyed.

Stylo doesn't have a good equivalent for restyle hints to expose in markers and

At the same time, several animation restyle tests currently use the hint inside
the marker to check when animation-only restyles have happened. We can preserve
this by changing the data inside the marker to be a flag for whether the restyle

Most of this patch is updating a few places that use gfxMatrix to use
the equivalent-but-differently-named functions on MatrixDouble:
- Translate/Rotate/Scale get turned into PreTranslate/PreRotate/PreScale
- Transform(Point) gets turned into TransformPoint(Point)
- gfxMatrix::TransformBounds(gfxRect) gets turned into
gfxRect::TransformBoundsBy(gfxMatrix).
- gfxMatrix::Transform(gfxRect) gets turned into
gfxRect::TransformBy(gfxMatrix).
The last two functions are added in this patch as convenience wrappers
to gfxRect instead of Matrix.h because we don't want Matrix.h to "know"
about gfxRect (to avoid adding gecko dependencies on Moz2D). Once we
turn gfxRect into a typedef for RectDouble these will be eliminated
anyway.

Using SVG SMIL it is possible to animate the class attribute of an element using
markup such as the following:
<style>
.red {
fill: red;
}
</style>
<svg>
<circle cx="50" cy="50" r="30" fill="blue">
<set attributeName="class" to="red" begin="1s"/>
</circle>
</svg>
In Gecko, Element::GetClasses handles this case by looking for an animated class
string when the element in question is an SVG element.
This patch causes our Servo bindings to use GetClasses when querying attribute
values for selector matching.
Note that animating the class attribute is *not* expected to affect attribute
selectors such as `circle[class="red"]`. It does in Chrome, but that is due to
a Blink bug where animating attributes using SMIL affects the result of
getAttribute:
https://bugs.chromium.org/p/chromium/issues/detail?id=735820
This patch adjusts the behavior for both the GeckoElement case and the
ServoElementSnapshot case.

Deduct timeout execution time from a continuously regenerating
execution budget. Then throttle timeouts by using that budget in
TimeoutManager::MinSchedulingDelay to adjust the minimum value if
the budget is negative. The minimum value is adjusted to be a
value where the budget would have regenerated to be +0 ms.
The execution budget is clamped by values in ms defined in prefs:
* dom.timeout.background_throttling_max_budget: 50
* dom.timeout.foreground_throttling_max_budget: -1
A value equal or less than 0 means that the budget is infinite.
The regeneration rate can be controlled by the following prefs:
* dom.timeout.background_budget_regeneration_rate
* dom.timeout.foreground_budget_regeneration_rate
one each for foreground and background throttling.
To not starve timeouts indefinitely we clamp the minimum delay using
the pref:
* dom.timeout.budget_throttling_max_delay: 15000
The feature is behind the pref:
* dom.timeout.enable_budget_timer_throttling

The problem here is that the server is setting the Content-Length to the size
of the gzipped file, which is confusing our media code as that's not the length
of the decompressed stream. Necko's decompressor is streaming, so we can't know
the length of the stream in advance unless we wait for the entire file to
download first. We also can't seek in compressed HTTP resources anyway.
So just have our code assume that compressed HTTP channels are of infinite
length and have un unseekable transport. Then we can seek in the buffered
regions at least.

Currently we resolve a property by iterating every prefable and check whether it
is enabled. If it is, we linear search the ids that it manages. This patch
changes that to binary searching to find whether the id being resolved is
present first, and checking whether its prefable is enabled only when we find
it. This improves the performance of property resolution, especially when the
property is not present.
The patch stores all the property ids a NativePropertiesN owns in a single array
of PropertyInfo structs. Each struct contains an id and the information needed
to find the corresponding Prefable for the enabled check, as well as the
information needed to find the correct property descriptor in the Prefable. We
also store an array of indices into the PropertyInfo array, sorted by bits of
the corresponding jsid. Given a jsid, this allows us to binary search for the
index of the corresponding PropertyInfo, if any. The index array requires 2
bytes for each property, which is ~20k across all our bindings. The extra
information stored in each PropertyInfo requires 4 bytes for each property,
which is about 40k across all our bindings in 32-bit builds, or 80k in 64-bit
builds due to alignment requirements on PropertyInfo. However we save a bit of
memory from changing NativePropertiesN's trios to duos.
The array of unsorted ids is kept because XrayOwnPropertyKeys() includes only
properties that are enabled. Without it, we will need to check every single
property to know whether its prefable is enabled or not, which is inefficient.
With this patch, initializing property ids takes longer because of the sorting.
I measured also insertion sort because I thought the ids should be nearly sorted
as they are generated sequentially at run time, but that's not the case and
NS_QuickSort() runs faster.

ContentEventHandler::ExpandToClusterBoundary() doesn't check the return value of nsTextFrame::PeekOffsetCharacter(). Therefore, it may set its result to reversed offset. (e.g., when aForward is true and offset is 6, the result may be 5. When aForward is false and offset is 5, the result may be 6.)
For avoiding that, ContentEventHandler::ExpandToClusterBoundary() should check the result and only when it returns nsIFrame::FOUND, it should compute the proper offset.
On the other hand, it's too bad for ContentEventHandler that nsTextFrame::PeekOffsetCharacter() to return nsIFrame::CONTINUE_UNSELECTABLE when the user-select style is "all" because IME doesn't expect such cases.
Therefore, this patch adds additional argument to nsIFrame::PeekOffsetCharacter(), aOptions which is a struct containing bool members. The reason why it's not a bit mask enum is, such struct doesn't cause simple mistake at checking the value and the code is shorter. When mIgnoreUserStyleAll of it is true, this patch makes nsTextFrame not return nsIFrame::CONTINUE_UNSELECTABLE.

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
