Those can't be ordered at specified / computed value time, since the
percentage basis could be negative.
Needs tests of course, running through try atm.

This prevents incorrectly reusing cached results when the contents go
away and new contents are allocated with the same address.
Note that these keep alive transitively everything else under them, so
all other medialist keys don't need this.
By making this a proper hashmap it should also improve cache lookup
times if the cache grows too big.

They are not. The serialization code already checks if the result is
empty, which can happen for other reasons. This makes the code a bit
more resilient to misuse.

But in this case the transform property wouldn't apply to the element so
there's no reason to create a stacking-context.

This should be mostly straight-forward, since we have code for this
anyways for image-set() and srcset.
The only thing is that we were using floats for resolution, but since
EXIF allows you to scale each axis separately, we now need to pass an
image::Resolution instead.
The main outstanding issue is the spec comment mentioned in the previous
patch, about what happens if you have srcset/image-set and the image
density specified together. For now I've implemented what the
image-set() spec says, but this is subject to change before shipping of
course.

It's the wrong pseudo-class name! Plus, it's not really needed, just
override the page styles temporarily.
Remove the pseudo-class, since it's its only remaining usage.

So that sheets are properly marked as committed. The issue is that we
have this "committed" optimization, to avoid doing work if somebody adds
and removes an stylesheet without us flushing in the meantime:
https://searchfox.org/mozilla-central/rev/f018480dfed4fc583703a5770a6db9ab9dc0fb99/servo/components/style/stylesheet_set.rs#308-319
The "committed" bit is set when we consume the flusher (in each(..)).
However when we hit the cache, before this patch, we wouldn't consume
it, which means that we may fail to do some full rebuilds even though we
need them.
Fix it by making sure we call each() in that case.
We add a test (the test would show a red square before this patch, and a
lime square with the fix).

This will allow detecting the system theme, which allows fixing some of
the blocked bugs.
Note that when using the system theme we will still match light or dark
appropriately, so this shouldn't change behavior just yet.

We had about 9 gaps / unused bits. I moved the devtools ones at the end
because I think we should be able to remove them (but separate bug).

We should just restore the state when seeing whitespace and an unknown
token like when we do when finding any other token a few lines below.
This is not an issue for most callers (it's only an issue for clamp())
because the other callers use either `parse_comma_separated()` (for
min/max), or `parse_nested_block()` (for parens / nested calc()).
Both of those functions restrict the input in such a way that
is_exhausted returns true (a few lines above) and thus we parse
successfully.

Astounding that there was literally no WPT for this at all. I added three: one
for backgrounds, one for list-style-image, and one for `content`. Cursor is not
handled on this patch because that one requires a fair amount of extra work.

This adds a new @media query -moz-toolbar-prefers-color-scheme which works like
prefers-color-scheme but is set based on the browser theme rather than the OS
theme. The background colour of the toolbar is used to determine the theme
dark/light preference. This will be used for in-content common.css pages and
other UI elements that include that stylesheet in the browser-chrome through
shadow DOM.
The end result is that about: pages, infobars, and modals will now "match" the
browser theme (just light/dark mode, not LWT theming support).

Safari does this. This reduces the runtime in the example linked from
comment 0 quite a lot (40ms on a local opt build, from ~130ms on a
release nightly build).
I added a pref because there's a slight chance of performance
regressions on pages that do not use attribute selectors, as we're now
doing more unconditional work per element (adding the attributes to the
bloom filter). But the trade-off should be worth it, I think.

No behavior change, just cleanup. Actually seem this technically _adds_ some code even
though it's a cleanup, but that's mostly because of the wrapping of the
derive list. The resulting code is simpler (more in-line with our usual
things, so I think it's an improvement).
