Due to the syntax limitation in failures.list, I cannot mark
multicol-rule-004.xht as fails with column-span enabled and success with
column-span disabled simultaneously. Luckily, we had another copy of it
in testing/web-platform/tests/css/css-multicol/multicol-rule-004.xht, We
can use it to test with column-span disabled for now.

Bug 1547939 added a bunch of extra tests for three properties (background, mask,
and -webkit-mask). This made them time out more frequently in the Android
emulator.
Request a longer timeout to address this. Alternative is maybe just removing the
tests or such, I don't think they're of particularly great value.

I'm still wondering why is bing.com doing this but oh well. This should address
the regression and probably even improve it.
I don't think these documents are observable from content (at least I haven't
found how) so this should be safe. Let me know if you want me to just wrap the
whole stylesheet in an `@media (width > 0) and (height > 0)` rule or such.

This is a first step towards allowing (some) batching work to be
done during prepare_prims pass rather than render pass building.
This is prep work related to output different batch lists for a given
picture (e.g. a different batch list per dirty region), rather than
replaying the same batch list.

This early return is just an optimization to prevent the DAG from becoming too complex, and if we're keeping the list linked, then we know it won't be getting more complex on the current paint.
Future paints that actually modify the list will still take this path.

The comment in nsDisplayTransform::GetTransformForRendering() clearly
says that |aOutOrigin| should return the same offset as GetTransform().
GetTransform() will pass the offset to GetResultingTransformMatrix()
which will round it in many cases to avoid subpixel blurry rendering.
But GetTransformForRendering() doesn't take this rounding into account,
thus contradicting the intent described by the comment.
This rounding is important to keep subpixel behavior consistent with
or without webrender enabled. Currently, SVG will be rendered blurry
in some cases if it's at a subpixel position. After fixing the problem
in non-webrender case, the strange blur still occurs in webrender case.
It turns out to be caused by this inconsistency.

We should snap subpixel value at nsDisplayTransform::GetResultingTransformMatrix
for outer svg and the anon child. This will solve blurry rendering for subpixel position
when webrender is __not__ enabled.

This patch makes widget use `mozilla::PresShell` directly rather than via
`nsIPresShell` and changes some pure virtual methods of `nsIPresShell` which
called by widget to `mozilla::PresShell`'s non-virtual methods.

We always include the combinator for pseudo-elements now (not including it was
just an optimization) in order to not match when nested pseudo-elements are
involved.
We could add a more generic check in `matches_simple_selector` like:
```
if element.is_pseudo_element() {
match *selector {
Component::PseudoElement(..) |
Component::NonTSPseudoClass(..) => {},
_ => return false,
}
}
```
But even that wouldn't be enough to make selectors like `:hover::marker` not
match on the `::before::marker` pseudo-element, plus that code is really hot.
So for now do the check on the `next_element_for_combinator` function. It's a
bit hacky but it's the best I could came up with...
While at it, simplify some checks to use is_pseudo_element() instead of
implemented_pseudo_element() directly.
Only the Rust patch as-is would make markers for ::before and ::after on list
items not show up, so we also need to switch ::marker to use ProbeMarkerStyle()
rather than ProbePseudoElementStyle(), since the marker should exist even if it
matches no rules.

This won't reintroduce any of the regressions that were triggered by our
previous attempts to turn off -moz prefixed gradients, and lets us massively
simplify the gradient code, if it sticks.

The previous commit removed the dependence on the discriminant value, so we
don't need to keep discriminants different from text-align anymore.

They do nothing, if they get parsed, they end up doing the same as text-align:
start, which is the same that we'd get out of GetLogicalAlign if the attribute
wasn't parsed in the first place.
We don't use this attribute for anything else like attribute mapping, so this
should be an idempotent patch.

`CapturingContentInfo` struct is used only in `PresShell.cpp` so that we can
make it a private struct of `PresShell` if we move all users of them,
i.e., API to access them, from `nsIPresShell` to `PresShell`.

`nsIPresShell::ScrollAxis` can be used anywhere and it's used by some
utils actually. So, it should be in `mozilla` namespace and perhaps,
`PresShellForwards.h` is a good place to move it rather than creating
new header file.
