It's only meaningfully read in two places:

* Some widget DEBUG-only code, which on Linux is ifdef'd and on Windows does
some rather sketchy things like sleeping for 30ms

Currently, checking whether an `EventTarget` is `nsINode` (or its concrete
classes) or not requires a QI, but it's expensive and used a lot while we
handle each event. Therefore, it'd be nicer for creating a virtual method,
`EventTarget::IsNode()` and use it for the check.
If trying to convert `EventTarget` to a concrete class, it may require two
virtual method calls. I'm not sure whether it's cheaper than a QI, but at
least, it won't depend on the UUID check order of `QueryInterface()` when
multiple interfaces are implemented.

this.browser in toolkit/actors/ControllersParent.jsm is the top level browser, ie the browser holding the root content document. So the conversion that happens in that file converts the coordinates to be relative to the root content document, but they need to be relative to the root of whichever child process we are sending the event to.
The best way I found out how to do this was to pass the coords down to the child process still relative to the parent process widget and then in the child process use the child to parent transform matrix to make them relative to the root widget in the child process.

On a long press touch event we fire a contextmenu event and if the contextmenu
is opening, we fire a touchcancel event. Unfortunately we had been checking
the return value, nsEventStatus, from nsIWidget::DispatchInputEvent via
nsContentUtils::SendMouseEvent to tell whether the context menu is opening or
not. So, we unintentionally fire the touchcancel event if the context menu is
NOT going to be opened because of preventDefault() in a contextmenu event
listener in the content itself.
NOTE: The oparator<< for the new PreventDefaultResult enum will be used in
APZ logging code.

Similifies use of EventStates and ObjectType/FallbackType enums since most states they represented are no longer valid with the removal of NPAPI plugins. The state machine for (unsupported) plugin elements is now much simpler but still distinguishes between HTML fallbacks, fallbacks leading to a "BROKEN" state (e.g. failing to load the image the element refers to), and fallbacks that would simply lead the element to occupy an empty region. The last type of fallback is behind a pref "layout.use-plugin-fallback" and is disabled by default.
Simplifying the state machine allows us to clean up nsObjectLoadingContent. We also update many of the enums which refered to plugins, which would otherwise get confusing.

Currently, it takes a raw native message value, but it makes JS content too
complicated. And on Linux, it cannot synthesize non-primary button events
because GDK has only button press and release messages which dont' include
mouse button information.
For solving these problems, this patch creates a new abstract native message
as `nsIWidget::NativeMouseMessage` and makes each widget converts it to
a platform native message.
Additionally, this patch adds an argument to make it possible its callers
to specify pressing or releasing mouse button with a DOM mouse button value.
Note that the following patch adds new argument to
`synthesizeNativeEventMouse*` for mochitests and which will be tested by

Now, there are no users of this API. However,
`nsIWidget::SynthesizeNativeMouseMove()` is still used by `EventStateManager`.

Unfortunately, I'm not so familiar with Android API, and in the short
term, I don't need the support on Android. Therefore, this patch just
adds a TODO comment on Android widget.

There are no code changes, only #include changes.
It was a fairly mechanical process: Search for all "AUTO_PROFILER_LABEL", and in each file, if only labels are used, convert "GeckoProfiler.h" into "ProfilerLabels.h" (or just add that last one where needed).
In some files, there were also some marker calls but no other profiler-related calls, in these cases "GeckoProfiler.h" was replaced with both "ProfilerLabels.h" and "ProfilerMarkers.h", which still helps in reducing the use of the all-encompassing "GeckoProfiler.h".

In OOP iframes, we don't have desktop zoom value specifically in each iframe
documents, instead we have a transform matrix,
nsIWidget::WidgetToTopLevelWidgetTransform(), on each the __top__ level OOP
iframe document that the matrix includes the desktop zoom scale value along with
translations by ancestor scroll containers, ancestor CSS transforms, etc.
Note that if the document is not in OOP iframes, i.e. it's in the top level
content subtree, the transform, nsIWidget::WidgetToTopLevelWidgetTransform()
doesn't include the destktop zoom value, so for documents in the top level
content document subtree, ViewportUtils::DocumentRelativeLayoutToVisual applies

We introduce a new type of display port, a minimal display port. It is controlled via a property on the content element. When the property is present any other display port specified on the element is ignored and instead the display port rect is computed by assuming 0 display port margins and no alignment (this reuses the existing code for display port suppression).
We then add code to set a minimal display port on every scroll frame that is painted that has WantAsyncScroll() when certain prefs are set (the prefs are disabled as of this patch though).
We then need to manage removing the minimal display port property when, before this patch, we would have created a regular display port. As well we need to add the minimal display port property when, before this patch, we would have removed a regular display port.
In order to do this I audited all sites where we set the display port rect and display port margins property. The changes to the code for handling the removal display ports happens in a later patch.
My audit found that all of the places we set a display port want to clear the minimal display port property except:
-UpdateSub/RootFrame in APZCCallbackHelper
-UpdateDisplayPortMarginsForPendingMetrics in DisplayPortUtils
UpdateDisplayPortMarginsForPendingMetrics is basically a fast path of the UpdateSub/RootFrame code. These are the places where we handle calls to RequestContentRepaint from apz. By adding an assert and running it through try server I found that UpdateSub/RootFrame can create a display port in the following cases:
-a scroll info layer
-a scroll frame with !WantAsyncScroll() (the main thread never creates a display port for a scroll frame with !WantAsyncScroll()) (for example if the main thread creates a scroll id and sends over metadata via nsLayoutUtils::GetRootMetaData, and then the scroll rect changes, that will cause a RequestContentRepaint call)
-a few instances that don't fall into the above that happened on try server but didn't reproduce for me locally, so I don't know more about them.
It's not very important whether we clear the minimal display port property for these cases or not (the first two cases we don't async scroll the scroll frame at all, the last case seems quite rare).
Note that we intentionally do not change the existing behaviour of zero margin display ports set via SetZeroMarginDisplayPortOnAsyncScrollableAncestors as we are aiming for no behaviour changes with this patch (until we flip the pref). A later patch in a different bug handles changing these display ports over to minimal display ports.

OneShotPostRefreshObserver works as the caller registers it, and
let it deletes itself via the DidRefresh method. The issue is that
DidRefresh is not guaranteed to run, and it'll leak PresShell
if it doesn't run.
This patch allows nsPresContext to store and release the last
registered OneShotPostRefreshObserver, and converted the existing
usage of OneShotPostRefreshObserver to use that. So instead of asking
OneShotPostRefreshObserver to delete itself, we now ask nsPresContext

There are two issues in our current setup
1) Input events which are occurring in the same tab are going to be lost
because sync XHR. We have event handling suppression for synx XHR, so input
events are going to be discarded.
2) Input events that are happening in another tab (same process as the
synx XHR tab) are not going to be delayed. This is not correct since
sync XHR should block the Javascript execution.
This patches fixes the above cases for when both TaskController and e10s are
enabled by suspending the InputTaskManager during sync XHR, which
delays the input event handling and keeps the events around.
