We don't have lossy currentcolor in the style system anymore, except for a
single property -moz-font-smoothing-background-color.
I could've converted it into a proper StyleColor and thread down all the
necessary information to the font metrics code.
But it doesn't really seem worth it given it's not exposed to the web, so I just
did the simplest thing, which is making currentcolor compute to transparent to
that specific property.
This patch also removes the stores_complex_colors_lossily code and related,
since now we always can cache computed colors.

With the current code we'll eventually detect the cycle, but will take much
more, creating many shadow trees unnecessarily. Take for example the following:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="133" height="232774">
<style>
symbol { display: block }
</style>
<symbol id="svg-sprite" viewBox="0 0 133 230866">
<title>svg-sprite</title>
<symbol id="svg-sprite" viewBox="0 0 133 230866">
<title>svg-sprite</title>
<use xlink:href="#svg-sprite" width="500" height="500" />
</symbol>
<use xlink:href="#svg-sprite" y="1601" width="133" height="228958" />
</symbol>
<use xlink:href="#svg-sprite" y="1601" width="133" height="230866" />
</svg>
Before this patch, we'd create an svg use element subtree for #svg-sprite. That
subtree will contain two other <use> elements, one under the <symbol>, one not
under it.
Both point to #svg-sprite, but we fail to detect we're an ancestor since the
element #svg-sprite we're looking at is the clone of the #svg-sprite element.
Thus we need to take a look at mOriginal instead (which is the <use> element
under #svg-sprite) rather than at the clone.
Yeah, I had to draw the trees, it's messy :)
Blink and WebKit do something slightly different (they check the element id
directly[1]). That's not 100% correct, since you can have multiple elements with
the same ID.

As it turns out we need this to avoid losing precision both during painting and
during serialization.
This patch also changes to serialize `context-value` if it's the computed value.
I could keep the previous behavior, but it makes no sense to serialize the
initial value. We're the only ones to support this value anyway, and I couldn't
find a definition or spec for this.
Also update tests and expectations for:
* New unexpected passes.
* Always serializing the unit in getComputedStyle.
* Calc and interpolation support.
Chrome also always serializes the unit in getComputedStyle, so I'm pretty sure
this is compatible with them. Chrome is inconsistent and keeps numbers in
specified style, but that's inconsistent with itself and with other quirky
lengths, so I updated the tests instead.
Differential Revision: https://phabricator.services.mozilla.com/D21819
Instead of storing them as LengthPercentage | Number, always store as
LengthPercentage, and use the unitless length quirk to parse numbers instead.
Further cleanups to use the rust representation can happen as a followup, which
will also get rid of the boolean argument (since we can poke at the rust length
itself). That's why I didn't bother to convert it to an enum class yet.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This hopefully will address the test-verify failures that were reported in bug 1516006.

All classes deriving from nsIFrame that did not have any subclasses themselves
(at the time of writing this patch) have been marked with `final`.
Some other Layout classes have also been made final, but this was opportunistic
while working on nsIFrame subclasses, and is definitely not exhaustive, further
patches welcome; refer to bug 1332680.
Advantages of marking a class final include:
- Allowing the compiler to devirtualize some method calls (i.e., calling
virtual functions directly instead of going through the vtable),
- Indicating that the class is not currently subclassed,
- Preventing subclassing without being aware that this would remove the
finalization benefits of the parent class.
`final` does not signify that these classes should *never* be subclassed, this
is left for developers to decide.

This flag and function name are used for both basic shapes and path function,
so rename it. For now, we treat path() and other basic-shapes as the
different object (i.e. StyleSVGPath and StyleBasicShape), so I rename
these functions and mask flag.

Create clip-path for the path function and reuse some APIs in
nsCSSClipPathInstance, so we don't have to update the code flow.

We end up with three <svg:use> elements to update (lol), because the target (#c)
changes, since we create another element with that ID in the document via
outerHTML.

For each file touched in this patch, the file had an #include for nsContentUtils.h, but no other mentions of the string "nsContentUtils", nor any mention of its "ScriptBlocker"-related types. So these files likely don't need their nsContentUtils.h include anymore, and we can remove it to get a marginal win on build time/complexity.

Now that the content is not anonymous we don't need to exclude them explicitly.
This happens because anonymous content inside the shadow tree does report to be
inside the shadow tree, which is true but at the same time slightly footgunny.
In any case the other uses of the use shadow tree stuff are base-uri related,
and changing anon content's base uri in that case sounds like the right thing,
even though anon content shouldn't rely on those anyway.

This is needed for patch 4.
This is based both on the wording in the spec and the discussion in
https://github.com/w3c/csswg-drafts/issues/2987, and also doesn't
support them for nsMathMLContainerFrame, which is similar to inlines and
ruby.

Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need
to match document rules, see the linked SVGWG issues.
But blocks_ancestor_combinators goes away, which is nice since it's on a very
hot path.
Test Plan: WPT for style invalidation, covered by existing tests otherwise.

In the case of an invalid clip-path, the browser is supposed to discard the
mask entirely. In the non-webrender codepath this would happen
implicitly because the computed MaskUsage would have no flags set, and
so no actions would be taken on the gfxContext which contained the
display items rasterized so far. In the WebRender codepath, though, we
invoke the code on a A8 drawtarget that's zero-filled, so if PaintMask
fails to rasterize anything into it, it gets treated as a "mask everything
out" mask. Instead, this patch makes it so that we detect the scenario
where the computed MaskUsage is a no-op, and ensure that we don't apply
the mask in that case.
An alternative approach considered was to initialize the A8 drawtarget to
white instead of black but in cases where there is an actual mask, the
rest of the code assumes it is zero-filled and so that doesn't work.

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

I'm replacing non-failing calls to NS_NOTREACHED with MOZ_ASSERT_UNREACHABLE, but this NS_NOTREACHED fails when running the dom/svg/crashtests/412104-1.svg test. This assertion failure is bug 903785.
This patch DOES NOT fix the cause of the assertion failure (a missing TextNodeCorrespondenceProperty). It just replaces this failing NS_NOTREACHED with NS_ERROR because I can't replace with a fatal MOZ_ASSERT_UNREACHABLE.

This was a memory-saving optimization introduced as part of dependencies for bug
686875, but a more general system landed in bug 77999 for Gecko and
https://github.com/servo/servo/pull/18509 for Servo.
So now it's probably even a bit of a pessimization (though probably not huge),
and given this causes bugs like bug 1462742, bug 1157592, and bug 1468145, and
fishiness like the one pointed out in this bug, we may as well remove it.
The performance impact of having to lookup through more rules should be minimal
given the bloom filter and the rule hash optimizations.
This makes me wonder whether we could remove the whole concept of on-demand UA
sheets, since they've caused pain, for example, when the frontend people try
loading <svg>s from NAC (since that triggers sheet loading from frame
construction, which is not good). I'm not concerned about loading mathml.css and
svg.css everywhere, though xul.css may not be as doable since it adds a bunch of
attribute-dependent selectors. Though on the other hand I asserted in the
xul.css code and we don't load it in content with <video> / <input
type="date/time/etc"> and such, afaict, so maybe now that legacy addons are gone
we can remove that sheet from content processes altogether.

Those changesets which are related to animations introduced in bug 1462497
seems to cause new crashes. I think the first two changesets for the bug fixed
the original crash cases but the last two (i.e. these changesets) introduced
other crashes unfortunately.

This ensures that the nsDisplaySVGWrapper's mFrame and its reference frame are the same frame: the nsSVGOuterSVGAnonChildFrame.
It'll also cause the nsDisplaySVGWrapper to be *inside* the nsDisplayTransform for the <svg> element's viewbox transform.
This patch reverts nsSVGOuterSVGFrame::BuildDisplayList to its pre-bug 1407938 form.
(That's the bug that introduced nsDisplaySVGWrapper.)
