Categories are useful to indicate: This much % of time was spent in this category.
The EVENTS category isn't a very good match for this. This category is currently
only set on labels of functions that handle the processing of an event. But
those functions are usually closer to the base of the stack, and the actual CPU
work during the processing of an event is usually in another category closer to
the top of the stack, e.g. in JS if we're running an event handler, or in LAYOUT
if we're hit testing the position of the event.
This changeset removes the EVENTS category and replaces all uses of it with the

In the case of a long-tap touch sequence, a new popup window (the
contextmenu) is spawned while the sequence is ongoing. The touch-end of
the sequence ends up getting delivered to the popup window, instead of
the original content window, and that causes the touch-handling
machinery state in the content window to get out of sync with reality.
This patch detects this scenario and redirects the touch events on the
popup window back to the original content window.

If a key combination causes text input, we need to dispatch keypress
events without alt/ctrl/meta modifiers since TextEditor won't handle
keyepress events whose altKey, ctrlKey or metaKey is true as inputting
text.
Currently, TextEventDispatcher sets mCharCode of eKeyPress event from
mKeyValue. Then, when altKey, ctrlKey or metaKey is true, it'll call
WillDispatchKeyboardEvent() and then, TextInputHandler needs to reset
the charCode value from native event information.
However, the problem is, TextInputHandler::InsertText() is called
with control character when control key is pressed and InsertText()
clears the modifier information before sending eKeyPress event to
TextEvenDispatcher so that TextEventDispatcher won't call
WillDispatchKeyboardEvent() even though control key is actually
pressed. Therefore, TextInputHandler cannot adjust charCode value
and modifier flags in some cases such as control + option + 'a'.
This patch makes InsertText() stop clearing the modifiers and
makes WillDispatchKeyboardEvent() do it instead. This procedure
is expected by TextEventDispatcher.

On macOS, option key is mapped to alt key, and it works like AltGr key on
the other platforms. Since our editor doesn't accept keypress events as
typing printable character if one of altKey, ctrlKey and metaKey of the
events is true, widget for macOS sets those attributes to false when an
editor has focus. On the other hand, if no editor has focus, our widget
does not do this hack so that altKey and ctrlKey values of keypress events
are always same as actual user operation and this is same behavior as the
other browsers. Therefore, we need to keep setting altKey of keypress
events to true if no editor has focus but we need to dispatch keypress
events even on content unless the charCode is 0.
So, only on macOS, WidgetKeyboardEvent::IsInputtingText() does not need
to check altKey state.

Releases the final reference to the IAudioSesionControl on a background thread in order to circumvent a hang at shutdown caused by stalled audio device interrupt handlers.
Previously, a feature was added to trigger pinch-zooming on desktops using the
mousewheel and a modifier key of the user's choosing (behind a pref).
To make testing easier on Macs, we wanted to trigger pinch-zooming
through Mac trackpad gestures. This patch enables pinch zooming through
trackpad gestures when the prefs apz.allow-zooming and
dom.meta-viewport.enabled are set to true. Currently, tests for this feature
were performed manually.
We will be using this feature only for internal testing. Later on when zooming
on desktops is more well-behaved, we will create automated tests and ship it.

The clip chain API in webrender allows us to build the clip state in WR
so that it matches the gecko display list more closely. This patch throws
away ScrollingLayersHelper.* and introduces ClipManager.* which pushes
the clip state to WR using the new method. A quick summary of the new
method is below.
Each display item in gecko has a DisplayItemClipChain which is a chain
of individual clips. The individual clips are defined in WR, and the
clip ids for those clips are put into a WR clip chain using the new
define_clip_chain API. Furthermore, each clip chain can also have a
parent chain, which is used to link a DisplayItemClipChain to the parent
display item's DisplayItemClipChain. This allows the WR clip state to
closely match the structure of the gecko display list clip state,
resulting in more correct behaviour.
There are a few other major changes that are lumped into this patch and
that were tricky to separate into their own patches:
- The collapsing of WrScrollId and WrStickyId into WrClipId. On the WR
side all the clip ids are treated the same anyway. Trying to preserve
the arbitrary distinction on the gecko side was resulting in
increasingly convoluted code, with different kinds of Variant<..>
types in the method signatures. It was much simpler and resulted in a
bunch of code deletion to just collapse the types.
- Moving the "override" mechanism from WebRenderAPI to ClipManager. The
override mechanism (explained in ClipManager.h) was simplified by
moving it into ClipManager, because it removed the need for tracking
additional clip stack state in WebRenderAPI.

We're already going to copy the data when we initialize the
nsISupportsString here. There's no need to copy the data into a
temporary object before passing it in to the nsISupportsString.
And as long as we're fixing the big mistakes, we might as well fix the
small ones, like copying the flavor string from the IPC object.
Remote WebExtension panels can cause us to recreate the widget for a view that
already has a size. In the past, popup widgets were always created with an
initial size of 0x0, so setting the initial size of the ChildView to 0x0
resulted in correct behavior because the window would be resized to the correct
size shortly afterwards, and resize the ChildView along with it via its auto
resizing mask.
When we recreate a widget which already has a known size, setting the initial
size to 0x0 is wrong. We need to set the ChildView's size so that it fills the
contentView of the popup window completely.
