The XUL behavior in nsBox.cpp is fairly different to what the non-XUL
layout code paths do. In particular, canOverride=false means that the
min-{width,height} properties cannot go under the min widget size of the
widget, but that doesn't mean that intrinsic sizes don't affect the
final size of the widget.
This is very visible if you turn on flex emulation on Windows or macOS,
where the toolbar has an appearance that returns
width=0,height=N,canOverride=false.
With flex emulation we'd collapse the item to be zero-width, which is
not good at all.
The good thing is that this is no longer exposed to the web
(non-native-theme always returns canOverride=true), and our front-end
code doesn't seem to rely on this, so we can just remove support for
canOverride=false.

In the description of the mTruncated bit, its purpose is the same as calling
SetInlineLineBreakBeforeAndReset(). We've removed all its usages in previous

Add a dom/base/rust crate called just "dom" where we can share these.
Most of the changes are automatic:
s/mozilla::EventStates/mozilla::dom::ElementState/
s/EventStates/ElementState/
s/NS_EVENT_STATE_/ElementState::/
s/NS_DOCUMENT_STATE_/DocumentState::/
And so on. This requires a new cbindgen version to avoid ugly casts for
large shifts.

There's only one meaningful usage of it, which is to disable native
appearance of the <input type=range> (the windows native theme is no
longer exposed to content).
<input type=range> is inconsistent with every other native widget, which
only disables native appearance if the author specifies backgrounds or
borders. So make it match literally all other widgets and simplify a bit
the code.
We had no tests for this special behavior, let me know if you think it's
worth adding one (but I don't feel very strongly about it).

This patch adds the struct as a parameter to various functions.
The struct is cached in ReflowInput so that we don't need to pass it
down to the internal method where nsIFrame::ComputeSize() is called.
In the subsequent patches, we'll use it to revise the implementation of
flex container's flex base size resolution, and size overrides.

This doesn't hold with fractional scale values. Right now GTK truncates
the scale factor, Windows rounds, and non-native theme rounds as well.
With this native theme will propagate correctly the floating point
values.
I tried to not change behavior meaningfully in any of the other themes,
mostly to avoid risk. GTK and Windows can be trivially tweaked to
support fractional scale factors properly if we wanted to, but seems
better to not do that as part of this patch.

The purpose of the dummy listener was to make APZ aware of the fact that
the range frame handles touch events without having any other explicit touch
listener. But we can do that more simply/cheaply by setting the eApzAwareListener

See https://bugzilla.mozilla.org/show_bug.cgi?id=932410#c2 for the
context for which this pseudo-element was added.
In the previous patch, I had to special-case range appearance because of
this pseudo-class, but that patch makes this pseudo-class completely
redundant, as now all form controls, themed and unthemed, display
outlines, unless the native theme displays a focus indicator on its own.
Remove the special case, and make ranges use outlines like everything
else rather than this bespoke pseudo-element.

Turns out we did have a hook for this already! But it is used to draw or
not inner button styles, so not quite equivalent.
I had to expand the amount of things it applies to because buttons and
such do paint focus indicators in all widgets. This patch could cause
some undesired outlines in some widgets. I hope not (I tried to audit to
the best of my knowledge), but in that case they'd be just more values
to add to the list.

This "upgrades" various nsLayoutUtils functions which take as inputs
a set of coordinates and a frame that the coordinates are relative to,
to accept a RelativeTo object instead of a frame.
Most of the patch is just dumb propagation, but the few places where
we use an explicit ViewportType::Visual are important. There are
probably a few other places I've overlooked, but this seems to cover
the important ones that come up commonly.
There are undoubtedly other functions into which we can propagate
RelativeTo, in this patch I've propagated it as far as necessary
for my needs in this bug (mainly GetTransformToAncestor() and
GetEventCoordinatesRelativeTo()).

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.
