Since the headless work (bug 1129492 and co) we realistically have no
way of rendering native scrollbars in any meaningful way. Remove dead
code that used to support using a different GTK theme on content.

To be honest, I'm a bit baffled that bug 1773795 caused a performance
regression, but I think it's because the standins codepath is not really
cached, so system colors that are "spoofed" always go through the
massive switch, which could potentially be expensive.
To fix, this, rejigger a bit the caches so that we key on both
color-scheme and use-standins. Also, while at it, make the set of colors
we spoof a single bitflag check, rather than relying on the compiler to
do something potentially smart with it.
I had to shuffle the order of colors around so that the expression to
initialize the bitfield is constexpr (doesn't go over 1 << 64), but
other than that this patch should be relatively straight-forward.

Eventually we should support all of them, but for now they are only used
by native code (unless you enable the color-scheme pref) and these will

And add code to use the appropriate variant like we do in macOS with
respect-system-appearance (but this still needs more work as noted in
StaticPrefList.yaml).
Still, it cleans up a bunch, and allows to not depend on the content
process boundary to provide light system colors.

After this patch, there are two remaining pieces to fix bug 1700294:
* macOS nsLookAndFeel needs to return the right colors for light / dark
appearance.
* We need to return ColorScheme::Dark for the right documents in
ColorSchemeForDocument.
Both of those should be straight-forward.

We also cache everywhere whether getting the int/float/color failed, for
example, and do the pref lookup on demand. Seems a bit nicer. We could insert
the pref values on the cache directly on Refresh(), that's another alternative,
but I don't think it matters much either way.
Differential Revision: https://phabricator.services.mozilla.com/D110675
Selection and accent color should be uncontroversial, since we ensure
the darker variant goes in the background, and the scrollbars were
intended to get passed from the parent theme in bug 1669368, but it was
regressed by the initial RemoteLookAndFeel work.

And make FontID's indexing setup more similar to FloatID / IntID / ColorID. The
values no longer need to match the style constants since Stylo. We could also
cache whether the lookup succeeded for floats / ints, but it might not be worth
it, your call though.

And re-enable the RemoteLookAndFeel by default with Gtk.
When the RemoteLookAndFeel is enabled and the non-native theme is not
enabled, we still need to configure the Gtk theme in content processes,
since we're still using Gtk to paint widget backgrounds etc. Without
this, we can end up using LookAndFeel colors from a light theme but
painting widget backgrounds from a dark theme.
Other platforms don't configure themes for content processes
differently, so on those platforms LookAndFeelTheme is an empty struct
and we skip the ConfigureTheme call.
Differential Revision: https://phabricator.services.mozilla.com/D100223
When the RemoteLookAndFeel is not in use, content processes override the
Gtk theme in some circumstances (e.g. if the theme is a dark variant, we
try choosing the light one, since that works better with Web content).
When the RemoteLookAndFeel is in use, the parent process needs to handle
this. So we temporarily set the parent process to the overridden theme,
extract the FullLookAndFeel data, then restore the original theme. We
make sure to avoid throwing away any cached data and restyling every
document as a result of the temporary theme change.

I don't think all this complexity is worth it for having a

Now both of GTK and MacOSX backends use the same machinery, LookAndFeelInt, for
prefers-reduced-motion. And we are going to use it on Android as well so it'd
make sense to move the code into there.
On Windows we can also use the same LookAndFeelInt machinery and probably
all we have to do is to call SendNotifyMessage with SPI_SETCLIENTAREAANIMATION
in SetPrefersReducedMotionOverrideForTest.

This should be an idempotent patch. The way to come up with this patch has been:
* Run the first script attached to the bug and pipe it to xclip, then paste it
in color.rs
* Add the relevant #[derive] annotations and remove the color.mako.rs
definition.
* Reorder the values to match the ColorID definition, on which some widget
prefs and caching stuff relies on.
* Manually port some documentation from nsLookAndFeel.h
* Run `rg 'eColorID_' | cut -d : -f 1 | sort | uniq >files`
* Run the second script attached to the bug.
* Manually fix usage of `LAST_COLOR` (adding the `End` variant), and adding
casts to integer as needed.
* Add an static assert so that people remember to update the prefs, rather than
a comment on the definition :)

So that we can query the test value in the child process properly.
Note that the APIs used for setting the prefers-reduced-motion value for testing
are only used on Android and MacOSX. As for MacOSX we have a different
machinery (see bug 1486971) to deliver the test value without spinning native
event loop in the child process so the change here is valid only for Android.

The framework to simulate the setting change works as following;
- nsIDOMWindowUtils.setPrefersReducedMotion() calls an IPC function which ends
up calling nsChildView::SetPrefersReducedMotion() in the parent process
- nsChildView::SetPrefersReducedMotion() sets the given value into
nsLookAndFeel::mPrefersReducedMotionCached just like we set the value queried
via NSWorkspace.accessibilityDisplayShouldReduceMotion in the parent process
and send a notification which is the same notification MacOSX sends when the
system setting changed
- Normally the cached value is cleared before quering new values since the
cache value is stale, but in this case the value is up-to-date one, so
nsChildView::SetPrefersReducedMotion() tells that we don't need to clear the
cache, and nsIDOMWindowUtils.resetPrefersReducedMotion() resets that state
of 'we don't need to clear the cache'
There are two test cases with the framework in this commit, one is just setting
the value and checking the value queried by window.matchMedia. The other one is
receiving 'change' event and checking the value of the event target.
Note that to make this test works the patch for bug 1478212 is necessary since
the test runs in an iframe.
