We already avoid scene rebuilding for animated image frame updates, but
we can easily apply this to still images. If the decoding is happening
slowly and in chunks for some reason (really large image, slow network),
then we may save some work.
This commit changes ScrollAnchorContainer to store the offset between the scroll anchoring
bounding rect start edge and the scroll-port start edge in the block axis of the scroll frame.
The logic to clamp the negative portions of scroll anchor bounding rect is also amended
to only clamp the portion that is beyond the border start edge in the block axis of the
scroll frame.

Performance of sync animation with large images is worse with WebRender than non-WebRender case. We want to use async animation as much as possible and relax aysnc animation size restriction. With WebRender, memory usage increase for async animation is limited compared to non-WebRender case. Image does not needs additional TextureClient allocation for async animation and majority of frames are comverted to WebRenderCommands. Then we could relax aysnc animation size restriction with WebRender.

This patch should make the detection of whether we should reframe in
UpdateContainingBlock exact.
It should have no behavior change, but sometimes reframing can confuse event
handling code or what not.
We don't have a reduced test-case for the event handling regression this fixes,
but I added a test to ensure we don't uselessly reframe in this case that fails
without this patch and passes with.

This patch implements -moz-gtk-csd-hide-titlebar-by-default media query
to check if the system titlebar should be disabled by default on Linux systems
(it's already disabled on Window/Mac).
It also removes explicit definition of browser.tabs.drawInTitlebar preference on Linux.
When browser.tabs.drawInTitlebar is missing the -moz-gtk-csd-hide-titlebar-by-default
is used to obtain the titlebar state. When browser.tabs.drawInTitlebar is set
in about:config or by Customize menu, the user peference is used instead of the default.
It also fixes a -moz-gtk-csd-available media query,
it was always true regardless the actual system setting.

The only thing using both was perspective, but that's not really needed with the current setup.
This more closely matches Gecko, too.

I believe that changes to 'overflow-anchor' should invalidate the current
scroll anchor. This isn't in the spec, but there's an issue open for it [1].

This commit adds two new telemetry probes to collect:
1. The amount of scroll anchoring adjustments applied
2. The total absolute length in CSS pixels of scroll anchoring adjustments
Both of these metrics are collected on a per top-level-document basis, and
reported with other use-counters.

We currently perform anchor adjustment in three spots:
1. If the target of RestyleManager::RecomputePosition is in a scroll anchor chain
2. If the reflow root is in a scroll anchor chain
3. In nsHTMLScrollFrame::DidReflow, for itself
It looks like it's possible for a scroll anchor container to be adjusted by (1)
and (2 or 3) in the same PresShell flush.
This should be okay, except that we consume mSuppressAnchorAdjustment when
performing an adjustment, and this can lead us to miss the second time that
we perform adjustments in a PresShell flush.
This commit reworks how we run anchor adjustments so that we collect all
scroll anchor containers that should be adjusted, and only perform the
adjustments once.

The tests for Bug 1133905 all compare the visibility of scrollbars with
differently-sized css viewports. This patch has some affect on the
viewport sizing that I don't understand, and it causes some of the tests
to start passing and some to start failing.
The test for Bug 1242172 has elements sized to height 100% and checking
for the presence or absence of scrollbars. In this case the patch appears
to increase the css viewport height and decrease the width -- again for
reasons I don't understand -- and this affects the scrollbar sizes.

Bug 1509717 removed Gecko's definition of StyleBorderStyle to use the Rust one.
The Rust version was ordered in a different way, and the table code relied on
the order in order to build the mapping for border conflict resolution.
Simplify this mapping now that border constants are ordered in terms of
priority, see the comment on top of `enum BorderStyle`.

The only reason it was on style_traits is so that they could use it from some
other crates, but Servo eventually ends up getting the value from an integer, so
may as well pass it around and do that in the end of the process anyway.

sizetopopup is set to "pref" by default by the menulist XBL binding, however
when converting the binding to custom element, it did not set the attribute value
at a time that is early enough.
This patch updates nsMenuPopupFrame and nsMenuFrame so that it considers
<menulist> with unset sizetopopup attribute as equal to "pref" to avoid
the problem above.
This reftest
layout/reftests/xul/menulist-shrinkwrap-2.xul
can detect this failure.
The sizetopopup attribute is never meant to be set dynamically;
the fix here does not allow us to do so.

This patch makes us handle calc with percentages when we can convert to
percentages the same way we handle plain percentages in table layout.
We still treat length + percentage as auto (this matches Blink / WebKit as
well). There's one case we differ with Blink / WebKit, which is calc(% + 0px),
which they'd treat as auto instead of a percentage.
I think this is a bug on them (or at least worth some spec clarification). I
filed https://github.com/w3c/csswg-drafts/issues/3482 for that.
In practice what that'd means for us if the WG decides that Blink / WebKit is
right in that case is that we'd need to keep track of whether the calc()
specifies lengths, and return false from ConvertsToPercent if so.
In any case, nothing that would massively change this patch, and I think enough
of an edge case that is not worth blocking on the CSSWG decision here. Though I
could be convinced otherwise of course.
