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
to release it.

Geckodriver doesn't support touch input yet, so convert new added the touch tests
into mochitest, these mochitest wpt could be removed once we could pass the
corresponding tests in wpt.
Depends on D101667

Calling setPointerCapture or releasePointerCapture in pointerup event handler would
throw error due to the active pointer is removed in PreHandlerEvent which is too
early. So defer removing active pointer to PostHandeEvent to make the active pointer
available in pointerup or pointercancel event handler.
This patch adds WPTs which has been verified on Chrome. geckodriver doesn't support
touch input yet, so mark tests for touch as expected ERROR for now.

This allows us to default to skipping the bundled Twemoji Mozilla font when running on Win8.1 or later,
where we can assume Segoe UI Emoji is available.
The new pref here replaces the existing pair of boolean prefs that were only supported on Android,
and is now respected on all platforms. Available settings are:
0 disable use of app-bundled fonts
> 0 enable use of app-bundled fonts
< 0 default (auto): decide at startup, based on the system environment
(The pref is relevant only at startup; changing its value during a session will not make the bundled fonts
appear/disappear dynamically.)

Instead, top level tile cache pictures are stored in the scene.
Follow up tasks in this bug will be simplified by having pictures
only exist when they have Some(..) for requested_composite_mode.
This patch removes one case of a pass-through picture, and
simplfies some of the surrounding code in the process.

Fetch the DRM device in the EGL version of glxtest, set it in gfxInfo and pass
it to gfxVars. Finally, use it in nsDMABufDevice::Configure().
While on it, also clean up EGL typedefs and defines a bit to match how it's
done for GLX.
Inspired by and copied from wlroots and Xwayland. Thanks to emersion!

This exception happens quite frequently with Fission enabled as we start observing requests
while the page already start loading. This happens frequently when target switching.

In `setErrorCount`, we used to call setToolboxButtons unconditionally, which means
that it was called each time a resource was added or updated.
This was very expensive and would cause some slowness, especially on pages with
a lot of network requests, as revealed by DAMP tests.
In this patch, we don't call setToolboxButtons if the error count did not change.
On top of that, we add a throttle mechanism so the function can't be called more
than twice per second.

If we know the Stencil is for a full parse, we can avoid extra traversals
during instantiation. Use the CanLazilyParse method from BytecodeCompiler to
determine if this is definitely a full parse.
