There's no reason we should need an scrollbar box to query the size of a
scrollbar. I plan to use this in the following patch to make the size of a
resizer not vary depending on whether the container has scrollbars or not,
which is what ultimately causes the reftest failure.

Forgot to follow up on these two remaining non-standard values that may have
been being used to reset a <meter> or <input type=number> back to its
original appearance, but which telemetry showed no usage of.

This implementation is more-or-less on par with the one from layout_2013
and in some cases better. There are still some cases where we don't
return the correct "resolved value," but this is enough to test
animations and transitions.
This patch computes the author-specified properties during the CSS cascade, and
removes the complex rule-tree-based implementation that tries to do the cascade
again.
This changes behavior in two ways, one of them which is not observable to
content, I believe:
* revert now re-enables the native styling. This was brought up in
https://github.com/w3c/csswg-drafts/issues/4777 and I think it is a bug-fix.
This is observable to content, and I'm adding a test for it.
* We don't look at inherited styles from our ancestors when `inherit` is
specified in a non-author stylesheet. This was introduced for bug 452969 but
we don't seem to inherit background anymore for file controls or such. It
seems back then file controls used to have a text-field.
I audited forms.css and ua.css and we don't explicitly inherit
padding / border / background-color into any nested form control.
We keep the distinction between border/background and padding, because the later
has some callers. I think we should try to align with Chromium in the long run
and remove the padding bit.
We need to give an appearance to the range-thumb and such so that we can assert
that we don't call HasAuthorSpecifiedRules on non-themed stuff. I used a new
internal value for that.

This should be less confusing. This is not supported outside of chrome:// or
user-agent stylesheets so we can name this however we want.

It is unexpected (see bug) that a -moz-box is affected by baseline alignment.
Make -moz-box be block-outside, and -moz-inline-box be inline-outside, instead
of the bespoke thing we have now.
This is more similar to everything else, and fixes the bug.

This matches the new servo layout engine too, and thus removes some #[cfg]
gunk. Just use `flow` since it doesn't simplify the layout code as much.

We always check StyleWillChangeBits_TRANSFORM bit together with a
transform-like property set, so using WillChangeBits::TRANSFORM bit to
represent all transform-like properties is ok.
However, it seems the new test case works well even if we don't have this
patch. I still add it for individual transform properties to make sure
the test coverage is enough anyway.

This is in the interests of allowing the frontend team to experiment with
switching from XUL grid to CSS grid, without inadvertently changing the
display values for the grid items via css-grid-item blockification.
This patch's new pref is not expected to remain in the codebase for long.
We're just adding it so that the behavior remains the same by default, because
we do currently have some XUL code that inadvertently depends on -moz-box
display values being blockified to 'block'. The plan is for folks to remove
that dependency e.g. by adding explicit 'display:block' styling to frontend
code as-needed. After we've done that, we can tentatively flip the pref to true
by default, and then remove the pref entirely.
